how much of the systems resources are being used when veiwing tv? how much ram installed? Have you tried another program to view the tv, other than mce. has this always been the case or just recently?
I doubt much of the system resources are being used. When I'm using media center, I'm not using anything else. This issue has only been recently (i.e., I only added [over-the-air] HD just barely.)
My TV tuner (ATI Theater 650, IIRC) has a[n analog] cable TV input and a digital [ATSC] antenna input. The cable input does not tune [unencrypted] QAM channels, so all of its channels are [SD] analog. The digital HD channels are tuned via the digitial antenna input.
As for
other programs to view tv signals, I have none. Media Center is all I have.
Anyway, here's a rundown of my system specs pertinent to the issue:
