I've tried the cvs-version of mpeg2dec.
The command
mpeg2dec -o pgm capturefile
gave me only grayscale pictures, with an odd size of 704x864.
The capturefile is an mpeg2 video-elementary stream (PAL), with an size of
704x576.
Any ideas to get colored pictures with the right size ?
Thanks Rupert

One approach would be to get the mpeg2dec package from linuxvideo.org It
will decode an mpeg 2 stream into frames, which can be stored to disk. I
think these frames are in YV12 format which can be directly displayed with
Xv on some graphics cards (Radeon for ex.)
mpeg2dec could probably be easily modified to capture only I frames to cut
down the disk-space requirements. It may then be as simple as
mpeg2dec -o pgm /dev/video
If you don't need to capture frames live, maybe cat the /dev/video to a file
first as in:
cat /dev/video > capturefile
mpeg2dec -o pgm capturefile
Let us know your results.
