Oh. Ok - but now you know another approach for the next time ;)

When something like that happens try using either 'head -1' or
'od -cb | more" to look at what is coming out of the previous
stage in the pipeline.
tccat | mplayer -vo yuv4mpeg | head -1
or
tccat | mplayer -vo yuv4mpeg | od -cb | more
Then check that there is indeed a valid YUV4MPEG2 header. At one
time mplayer had a bug in that the parameters in the generated
yuv4mpeg output were bogus and later programs would have problems.
If it's invalid a little shell script or utility to replace the
header will do the trick.
