I encoded a short high-motion scene to MPEG-2 with TMPGEnc, CCE Lite, and Ligos LSX. I playback the MPEG2 files to my TV screen through my Matrox e450 card, using the Matrox DVD player software.

The Ligos LSX MPEG2 files play back fine. The TMPGEnc and CCE Lite MPEG2 files both have the same problem: horizontal lines in the picture. The horizontal lines are wider than the comb-like lines one sees when there are interlacing issues. The strange thing is that if I convert those MPEG2 files back to an huffyuv-compressed AVI file, they playback fine to the TV screen.

Where is this problem coming from? Since they play back fine as AVI, but not as MPEG2 files, the problem might have to do with the MPEG2 player. But since the problem exists only with the TMPGEnc and CCE Lite MPEG2 files, not the Ligos LSX MPEG2 files, the problem might have something to do with the encoder.

Can anyone make any sense of this?
