Wrong: first (afaik)  there's no mpeg1-ts, only mpeg2-ts, second there's 
a standard  way
to put mpeg4-es (Audio/Video and even more) both  in mpeg2-ts and mpeg2-ps.

In my last patch to demux_ts I implemented one of the two ways to demux 
audio and video from -ts streams.

VLC can generate such files.
