Hey, are you sure your DEMUX is wrong?
Did you by any chance try to re-mux wit ha VOB (DVD) multiplexer?).
Then you get exactly that effect.
This HDTV is NOT DVD standard,

I did the following just now,
sat=hotbird
freq=11013
pol=h
sym=27500
vpid=272
apid=528
prog=10

Tuned with with xdipo, the recorded some 1.5 GB like this:
cat /dev/dvb/adapter0/dvr0 > q1.ts

The played with (latest) xine:
xine q1.ts
All in sync

Now made a .pes
cat q.ts | ts2pes 272 528 > q1.pes

Then demuxed:
es_demux q1.pes q1.mp2 q1.mpv

Listened to the mp2
mpg123 q1.mp2, no problems with audio.

Remux to VOB:
tcmplex-panteltje -i q1.mpv -0 q1.mp2 -m d -o q.vob
This gives thousand of warning about audio underflow, and the audio ends early.

BUT muxed like this:
nice -n 19 tcmplex-panteltje -i q1.mpv -0 q1.mp2 -m 2 -o q.mpg
gives a mpg tha tseems in sync (have not tested to the milli-second).

All software in http://panteltje.com/panteltje/dvd/
Any complaints to http://panteltje.com/panteltje/freewill.gif

That will be 100Euro
