is this even a known issue? I see a few posts, but Im suprised it could be just me... using a standard comcast motorola box and a panasonic ST Plasma. I would think if this were a systematic issue, this would be more commonly reported.
It starts out fine, but somewhere over the course of the hours, it gets off by some half a second or more. Ive done a full unplugged reboot a few times, a simple restart does resync things... For a time.
Restarting the cable box does not resolve it.
