The -vc switch doesn't help, error message is still the same. I also tried 
linking mplayer against the latest libmpeg2, but the result is the same: "bad 
sequence header extension"

So the problem in mplayer must be before codec comes in play, maybe in 
somewhere in the demuxer? 

Perhaps Nico can comment on this? 

If it helps I can provide some short transport stream samples.
