Comment (by Cigaes):

 I was about to ask the same question; no, pure {{{[ffmpeg2] vfm: ffmpeg
 (FFmpeg MPEG-2)}}}, and I get a lot of artifacts. If I add the following
 line in {{{vd_ffmpeg.c}}} after the call to {{{avcodec_decode_video2}}}:
 {{{
 printf("decode packet size %d/%d\n", ret, pkt.size);
 }}}
 I get very different results depending on whether I use {{{-demuxer
 lavf}}} or {{{-demuxer mpegts}}}: 4553/4553, 4185/4185, 14116/14116, vs.
 38035/38035, 2345/2345, 33803/33803, etc.

 OTOH, the video decodes fines with avplay, so maybe this is a problem in
 MPlayer's use of the demuxer and here would not be the place to talk about
 it, but this whole thing is highly confusing.
