The Horror...
I had an HP Pavilion Desktop Media Center PC too and I can tell you that it is a pain. After a month of getting TV tuners and going to repairs i finally gave up on it as it didn't work. A year later i discovered a small piece of paper inside the manual that said NOTICE: NOT ALL TV TUNERS WILL WORK WITH THIS SYSTEM
I don't know if you had yours included or not but somehow I had the same problem. i could not tune.
Yeah, it came with the card installed. It tunes just fine. I just can't get all the sub-channels in digital mode. Whatever channel (x)-1 is, that's what the tuner broadcasts.
I couldn't believe there wasn't even some sort of user guide for the remote. Everything I ever owned that came with a remote had a description and function of all the buttons.
With out knowing anything about the model tuner you're using, and just off the top of my head, did you rescan for new channels since you switched source modes?
Absolutely. It scanned in the channels and program info just fine. The problem is whe I go to channel 20 it shows whatever program on 20-1 but lists info for 20-2. (20.2 is the default anaolg channel here)
Without opening the thing up I have no idea of the tuner card either. I'm assuming HP installed the cheapest card they could get their hands on. I do know the video card is the NVIDIA GeForce 8500 GT.
