Hi there

You have a good question, but I have not done any transcoding to H.264/AVC. One issue is that the PQ of TV shows varies and overall is not all that great. I've downconverted a few episodes of "Lost" and "House" to DVD resolution, and then upconverted for playback on a 720p CRT projector. The difference in PQ is not obvious to me. Some of the travel and nature shows on PBS have great PQ. If only the commercial broadcast networks matched that picture quality!

When transcoding, the digital artifacts will accummulate. And because these are lossy compression schemes, information is lost with each encoding. The concept of "perfect digital copying" does not apply here. Hope somebody can give you an answer.

Regards
