Windows 7: Dual TV tuners and DVR recording

Dual TV tuners and DVR recording

It would seem that 7MC won't utilize both tuners when recording back to back programs on the same channel. What it will do is use one tuner and cut off the first program and start another recording.

Its really not apparent when there is a 6 minute comercial break between programing, but it is apparent when one program ends and the next starts right up.

I have played around with the "padding" under recorder defaults and have set them to 2min before and 2min after, going as far as 10min before/after trying to force the thing to switch tuners and nothing works. It simply cuts short to first program by 10mins.

I've tried playing with the "priority" settings and it seems to me that "priority" has no effect whatsoever.

I've tried going into the "series settings" and having it end 5min after without the "when possible". It would seem that the "recorder defaults" over rides the series settings.

I am quite sure the 2 tuners are configured correctly because I had to set them up with 2 stb and IR blasters and I can start a manual recording on channel 269 and then watch channel 5. It simply won't tune both tuners to channel 5 simeltaniously.

I don't remember having this problem with XP or Vista.

My tuners are Happage 1850 hybrids PCIe 1x with just the analog tuners having signal. The HD broadcast tuners are open.

Does anyone else have this problem? Is there a Fix around? or a Pluggin I can download?

As far as I know it will only record a few mins after when nothing else is recording.

When back to back shows need recording then it uses the specific time that one finishes and one starts. So bang on 10:00pm for example.

The only way to make sure one program isn't at the very end of the previous is to make sure your time is spot on. I don't think two tuners can record one channel.

And this is what I don't understand about Microsoft engineers...

1- No one syncs their time to the same server, and this is why "padding" is needed... Its not possible to have "exact" timing...

2- "Priority" is only a factor when there is only "one" tuner installed... otherwise its not needed...

3- When there is an unused tuner "why" can't it be tuned to the same channel as the channel being recorded? There are two seperate tuners and two seperate STBs and its possible to record two seperate streams... So where is the problem?

4- I can manually record the entire timeslot, but thats a pain... When series recording is automatic...

It used to work perfectly on XP and Vista, I don't see "why" they changed it... There must be a simple fix? A registry tweak or something...
