Fixed, turned out to be due to a partially initialized buffer. This was
also causing a problem with a PS file for Robert Johnston. It wasn't
really PS vs. TS recording related, the simply showed up more reliably
in HDTV recordings because the average distance in bytes between PAT 
and PMT tables is larger in HDTV recordings than in NTSC recordings.

Due to this fix, I need someone to test XvMC-VLD playback...

This is probably fixed, I don't have any non-MPEG recordings around
to test with. If someone could try playing a nuppelvideo recording
on an XvMC capable display I'd be grateful.

I haven't looked at this yet. I added an XSync and aquired the global
lock in Show, which may prevent the hard-lockup, but there is still
something wrong with either the XvMC OSD or XvMC pause frame code.

I also fixed a problem with LiveTV preview I forgot to mention in v10,
the width and height were transposed in the buffer init call of
VideoOutputNull. This resulted in some funny looking video...
