Sample file is truncated version of the original file which has been 
grabbed from Optelecom Siqura C-60.
I've left only two first pictures to minimize the problem. Original 
sample uploaded to 
ftp://upload.ffmpeg.org/MPlayer/incoming/interlaced_mpeg2/interlaced_mpeg2.bin
It can be successfully decoded by libmpeg2 tools. By the way, libmpeg2 
reports errors for exploit.bin and returns no frame but don't crash.
