I see the same effect on my system, which is a 3.06GHz Celeron D running
Ubuntu with output to an NTSC TV via either an nVidia MX4000 card or a SiS
Xabre 200 card. (I've been swapping video cards because of interference with
the QAM reception on a pcHDTV 3000 card, but I've not quite nailed that
problem down.) The problem seems worst with MPEG-2 sources, and possibly a
little worse with the nVidia card than with the SiS card.
There's another thread on what may be the same problem playing back DVDs;
here's the gossamer-threads URL:
The last post to that thread indicates that the problem went away after
compiling from source rather than using the Ubuntu binaries. I'm currently
running the Ubuntu binaries, so I may just try compiling MythTV from source.
