I understand. But given that you're feeding the HVR-1250 nothing but channel 3 via coax, you have to live within those constraints.

One constraint, of course, is that you're not watching true HD.

But the other is that you must always view and record using channel 3. NO other channel is delivered on that coax except channel 3, which corresponds to whatever actual channel the STB is tuned to at that moment.

There is NOTHING on the coax at any other channel but 3. Period.

the scheduled recording was set to record from channel 43(through wmc) and not channel 3. so this brings up the question. is there anyway to view the .wtv files i have recorded?
Not at all. You recorded nothing but some frequency on the coax.

There is nothing on your coax that has any meaning other than channel 3. Period.

I don't understand how you schedule recordings... because your WMC recording must be set to channel 3, and simultaneously you have to be sure the STB is on the true channel you want to be recording (in this case AMCHD on 43). How do you make that happen... manually? Some programmed Harmony remote or something that auto-tunes the STB via timer/programming?

And if you've recorded things in the past correctly, presumably those recordings were made using WMC and setting to channel 3. How/why did you mess up this time and set WMC to record channel 43? Temporary brain out-to-lunch?

Anyway, your WTV recordings of what was supposedly channel 43 are 100% worthless. The "copy protected" message is clearly not a true statement, but probably is just coming out because WMC can't figure out what it's looking at in that channel 43 WTV recording and assumes that it's encrypted or at least cannot be decrypted by what is supposed to be the active cablecard, hence it must be "from another computer recording".

Don't think about it anymore. The problem is now clear, that you mistakenly set the recording for channel 43 when in fact ALL your WMC recordings using this setup should ALWAYS BE ON CHANNEL 3, with the STB needing to be tuned properly at the same time to whatever true channel you wish to record via WMC/3.

actually i am using a wmc remote. the hvr-1250 , with a ir blaster remote, is compatible with wmc. i *always* record using wmc and schedule it to the channel i want. so something is not correct.

i never program wmc to record channel 3 and then tune the stb to channel i want to record. there is something else going on here as to why i cannot watch these .wtv files?

Well, I certainly have to state the obvious... that I have no firsthand experience with the HVR-1250 card, nor the configuration where an external STB feeds an internal tuner card via coax with WMC tuned to channel 3 (since that's all that comes from the STB to the tuner via coax) and yet you use WMC and the onscreen Guide to control the external STB via IR blaster controlled by WMC so that it gets tuned to channel 43 (or whatever) at the right time per the scheduled recording through WMC.

I appreciate the obvious "convenience" of having WMC do all of this stuff for you, i.e. controlling the IR blaster to actually tune the STB as needed, while at the same time letting you believe you're actually tuned to and watching that channel via the onscreen WMC Guide... when in fact it clearly is expecting and handling channel 3 coming into the TV tuner card through the coax. That WTV recording is actually from analog channel 3 arriving via coax, not digital channel 43 although we realize the true source is digital channel 43 on the STB.

But I've never actually used this setup.

Anyway, this "copy protected" symptom is in my opinion a completely inexplicable anomaly. No answer whatsoever. Obviously you have watched and probably recorded channel 43 before (tuned on the STB, delivered via channel 3 to the HVR-1250, but still seemingly channel 43 if you look at live/recorded info or Guide in WMC). You certainly said you just double-checked the same story with a 30-second recording from HBO and it worked fine.

And yet, when playing your AMCHD channel 43 recordings you show the "copy protected" message during playback, which is physically impossible to have occurred since the WTV recordings themselves are made on your WMC machine from the analog channel 3 input delivered via coax from the STB, which inherently cannot possibly have the digital copy-protection flags on it. Impossible. Physically impossible.

Obviously, some inexplicable anomaly. I certainly can't explain how it happened, nor can I even imagine any way it's possible to occur.

Why don't you try right now to again record something from AMCHD channel 43, and confirm that you do or do not have the exact same problem right now.

interesting. i just did a 30 second recording on channel 43. (amchd). when i open it using wmc all is well and it plays fine. when i try to open it with wmp (windows media player) i get the following message:

Windows Media Player cannot play, burn, rip, or sync the protected file because you do not have the appropriate rights.

the original walking dead files also generate this same message in wmp.

hmmmm...

This is indeed odd.

WMC is the only program alive that has the ability and authority to play "copy protected" WTV files. WMP on the same system CANNOT.

And that's because normally, when digital HDTV programs are recorded which are delivered through a cable system that marks the content as copy-once, the usability of that encrypted copy-once content is facilitated through the cablecard which is theoretically in the TV tuner card being managed by WMC.

The cablecard is what enables WMC to decrypt the encrypted digital transport stream provided by the cable system, either for watching live or for record/playback capability. Without the cablecard only copy-freely unencrypted clear QAM content from the cable system is usable... by both WMC and WMP. For copy-once encrypted content, only WMC can do the view/playback, and then only if a cablecard is present.

So... if in your situation where the external STB is the "tuner" controlled by WMC via IR blaster remote, and if the delivered content is true analog channel 3 to the HVR-1250 and thus recorded as pure unprotected 480i where there is no copy protection involved in creating the WTV recordings, it seems to me that there shouldn't be any problem with either WMC or WMP playing back such a WTV file. It's not HD, it's not from a digital source (i.e. it came in as analog channel 3 via coax and was converted to digital WTV via A-to-D MPEG conversion by WMC itself), and there shouldn't even be a copy-protect flag on the WTV file.

So I would have expected both WMC and WMP to play it fine. Certainly WMC should play everything it records and WMP wouldn't be able to play some WTV produced from digital copy-once input. But every one of these WTV files produced in your situation should be completely unprotected, as they arrive via 480i analog channel 3 through coax.

I don't have an answer yet. But there's no reason to want to use WMP, when WMC plays them fine, is there? At least you can play them with WMC (at least this most recent experimental snippet). Why are you trying to play them with WMP?

And, looking back at your original post, you didn't mention that you were getting this message from WMP. I assumed you were dealing with WMC, not WMP. Are you now saying that in fact all of those programs you complained about in your original post actually CAN be played successfully with WMC, and it's only when you try to play them with WMP that you get the "copy protected" error?

yes. which brings me back to 10 episodes of walking dead sitting on my hard drive and unplayable. frustrating indeed. thank you for trying!

I'm still confused.

Are you trying to play these with WMC or WMP??

Again, I can understand WMP not being able to play copy-protected content whereas WMC can play them. But this is only when there is digital 720p/1080i content involved which was delivered directly from cable company to an internal or external TV tuner containing a cablecard (e.g. Ceton's InfiniTV, or SilconDust HD HomeRun Prime) and which has been marked as "copy-once". In that case, only WMC can be used for playback of WTV recordings.

But in your case, with the external STB delivering analog channel 3 for recording by WMC, I'm truly mystified that there is any hint whatsoever in the WTV recordings made of copy protection... since the source (and 480i at that) was analog and not digital (720p/1080i). In this case BOTH WMC and WMP should have been able to play these WTV files.

For sure, WMC should have.

So to clarify your original post where you didn't mention WMC or WMP specifically, and I just assumed you were talking about WMC, are you now stating that you CAN or CANNOT play these files with either (a) WMC or (b) WMP? Two separate questions.

i originally was referring to wmc. i can not play these files in wmc. as an aside when i made my last 30 sec recording test of channel 43 (amc) i tried to play it back in wmc and wmp. but i'm only concerned with wmc...

Well, then we're back to the original story (now clarified, I guess). You theoretically did what you just experimented with a little while ago and had no problem at all using WMC... theoretically recording channel 43 with WMC for 30 seconds, and then playing it back with WMC, and it works fine. Did you set up a "timer recording", or did you just manually press REC while watching live?

And yet, your 10 episodes recorded previously (using timer recording technique)... for some reason they are NOT playable with WMC, and yet you believe you did exactly the same thing in terms of setting up the timer recording also from channel 43 using the exact technique you've always used without a problem.

I don't know what to say. Obviously there is something different about what you did when recording those 10 episodes, from what you just did as the 30-second experiment a little while ago.

It's simply impossible for WMC to complain about copy-protection when playing back a WTV recording made from analog channel 3. That's just not possible. But we're counting on WMC to realize that it needs to send out an IR blaster control to set the STB to digital channel 43, and also know that the input signal for recording through the HVR-1250 will be arriving on analog channel 3 via coax.

On the other hand, if something didn't go right, and WMC actually thought it was supposed to be recording actual digital channel 43 from the coax when we know full well there can't be a digital channel 43 on that coax fed from the coax output of the STB, well maybe this is where the issue was born. Perhaps playback of what must be a true garbage WTV recording of theoretical digital channel 43 is what is throwing that "copy protected" result from WMC. Don't know. No idea what's going on with any certainty. Pure speculation.

But if your recent 30-second experiment WAS once again successful (as I'm guessing it's always been before this unique 10-episode anomaly), then I'm afraid you're just going to have to deal with the loss of those 10 episodes. If they're re-aired, then set up another timer recording. Otherwise, sounds like they're history and we don't really know what you (or WMC) did differently that made them unusable.

in my 30 second tests i just hit record while watching live.hopefully they'll re-air before too long. thank you again for taking the time to try and help.
