is_sequence_needed never gets unset.  i printed the buffer i'm
passing into mpeg2_decode_data and i see a 0xb3 every few hundred
bytes.  i tried mpeg2dec-0.2.1-cvs -- it failed in the same way.
It seems like there is something strange about mpeg1 video steams
that confuses decode.c:copy_chunk.

What else can i try?  Do you want to reproduce this on your box?
