[MPlayer-users] Garbled/distorted video with MPEG-2 transport stream playback (DVB)

I use mplayer together with Freevo to record and playback DVB MPEG-2
transport streams. It works very well for this purpose, as the transport
stream is recorded with -dumpstream -dumpfile and can then be played
My problem is that sometimes, certain programmes on certain channels
cannot be played back. The video image is distorted, as if the
vertical/horizontal sync had been somehow lost. The picture looks the
same as an old CRT monitor with invalid frequencies, but this happens
"within" mplayer, inside the video window. (My screens are TFT anyway)
To be more specific, it happens at least with "Dr. Phil" on channel 4
here in Finland. The beginning commercials play fine, but when the
actual programme starts, the picture becomes distorted. At the same
time, mplayer prints out this, apparently detecting some change in the
MPEG2 encoding parameters:
VDec: vo config request - 704 x 576 (preferred csp: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
VO: [directx] 704x576 => 768x576 Planar YV12
The problem is present in 1.0pre7 and CVS-20050725, and happens on both
Linux and Windows, in both full-screen and windowed mode. It is not
related to freevo, as it happens also when playing back video manually
from command line.
Does anybody have suggestions what to do to fix it?

Never trust an operating system you don't have sources for.
