I've been working on this for several days now. My setup is XP, gbpvr1.3.11, ATI TV wonder 650, and using COX basic cable.
The problem is that some public HD channels(QAM) are not picked up in gb-pvr. I know it sounds very much like a signal strength issue, however, I don't think it's the case, because:
1. Catalyst Media center on the same sestup can pick up those channels without problem.
2. The ATI tuner can pick up many more HD channels than my HDTV. (of course those are unknown ones, which is encrypted) This means the tuner card is more sensitive.
3. If I change tuner mode to ATSC, the missing channel actually show up in the preview list. (yes, I know I won't be able to watch them since tuner mode are wrong) But this at least shows the signal is there and the card can see them.
The odd thing is missing channels all having a higher channel id, e.g., I can get 4.1,4.2, 5.1, 20.1...., but can't get 26.1, 26.2, 50.1.
I tried to follow this thread: http://forums.nextpvr.com/showthread.php...ight=tweak
but no luck so far. There are just so many BDA related config to tweak and I'm not sure their function.
One more thing, I have .net 3.5. The wiki said .net 2.0. I'm not sure if I should downgrade. But want to make sure this is the issue here.
