I'm running 2.03 and I'm noticing the audio and video is out of sync on nearly every channel. It's not consistant though. The problem comes and goes. It's very slight...if you're not looking for it, you won't notice it. It bothers me, but the wife doesn't notice. This is all on live TV. The worst by far is TNT. I noticed as soon as they started carrying the NASCAR races this season that the delay is at least 1/2 a second. Audio is always before video.
Yes, I've noticed once now that when watching a DVR event, if the picture signal burps, the audio and video goes out of sync. Stopping and resuming the program fixed it. I haven't seen a repeat of it yet.
