Yes. There's only MPEG-PS with PCM audio in it in the suite at present 
but the stream is 24-bit, which can't be muxed.

New FATE test attached. Removed the md5 test and added a framecrc test 
on a remuxed file since any bit flips due to other parts of the muxer 
should be disregarded.

Regards,
Gyan
