Eric,

You dumped a TS on disk. When I play it whith

vlc -V sdl --input ts dump.mpg

It does what you suspect to do. If you name it a .mpg, then you expect 
an MPEG file and not a TS file.


vlc tries by default a ps input and not an ts input as you need in this 
case. By the way I used the standard rpm for this version: vlc-0.2.92-1
