Windows 7: Windows 7 Media Center cannot find TV tuner card signal

Windows 7 Media Center cannot find TV tuner card signal

I have two computers. One a year old and one brand new. Both are running Windows 7 64 bit and both are running the exact same version of Windows Media Center. On my old computer I have my Windows Media Center TV configured for channel 3 and the cable attached to my internal TV Tuner card. Then, to access different channels I simply use the remote controller that came with my cable company set top box. Never any problems.
Now, I am trying for three days to have Windows Media Center set up the TV stations on my new computer. The device manager is finding the TV Tuner Card that I installed. All the drivers are up to date. I can use WinTV to find and play channels so I know there is signal coming from the cable...the same cable that feeds my old computer...I simply unhooked it and attached it to my new computer. So, it's driving me crazy that each time I try to scan for channels I wait for 10 minutes each time only to get a message at the end saying "no tv stations found" or something like that.
What could I possible be doing wrong since everything is the same between the old and the new computer?

I think if i remember right i read somewhere sometimes you have to go through and add everything manually. Have you checked the Manuals here specifically the wmc manual Hauppauge Computer Works : WinTV-HVR-2250 one more thing. There used to be a good forum for help one this but Microsoft bought it out go figure. For some reason the pdf files on there wont download for me. I found this Remapping clear QAM channels in Windows 7 Media Center Here are some instructions from HDTVTUNERINFO.COM on remapping clear QAM TV channels in Windows Media Center. WinTV-HVR-2250 Support page Direct Link to Guide How to setup Digital Cable in Windows 7 Media Center I think this should fix you up! It is normal to show no channels but follow that guide and that will get you your channels in media center.

I noticed in the link for windows media player setup (thanks for that link) that I am totally missing a step. I saw no install "Playready" at all in all the times I was trying to get this to work.

I cannot find any information on how to update Windows Media Player "Playready". It's missing when I try to configure live TV.

I think PlayReady is only relevant if WMC detects a cablecard-enabled TV tuner and you want to be able to accept copy-protected content from your cable provider. If WMC doesn't recognize such a digital cablecard-enabled tuner as being present, perhaps that's why it does not pop up that set in the initial setup wizard dialog.

I don't understand your setup. You have an external cable company STB, which feeds 75ohm RF-coax to the RF-coax "TV" input on your HVR-2250, and you then tune WMC permanently to channel 3 and do the real tuning on your external STB which delivers its tuned channel via channel 3 over the coax?

So what's the need to have WMC tune for channels? It's just channel 3 that you need.

Also, I believe this setup delivers 480i resolution in 4:3 size over this coax connection from STB to the HVR-2250 and channel 3. That's acceptable to you?

What is your cable provider? Are the channels you're interested in watching (albeit in 4:3 size and 480i resolution, rather than 16:9 720p/1080i HDTV) copy-freely or copy-protected? The HVR-2250 can accept clear-QAM (i.e. copy-freely) from your cable provider, so if that's sufficient for your viewing needs why not just connect the cable company coax directly to the HVR-2250? That would give you true 16:9 720p/1080i HDTV through WMC.

Have you considered revising your configuration to include a Ceton InfiniTV 4-tuner card (either internal or external USB)? This is a cablecard-enabled tuner so you could simply return your current STB to the cable company and use the Ceton card for both copy-freely and copy-protected channels, completely eliminating the need for your STB.

And then WMC would absolutely recognize the digital cable TV tuner presence, and would absolutely walk you through the install of PlayReady (which is the DRM software required by Cablelabs in order to allow cablecard-enabled tuners with WMC for copy-protected content).
