I also have totem-xine with dvb-t support it does not seem to have the
TS stream problems or neither the sound distortions.

I don't think the TS stream is damaged or that I have poor receptions,
because when I just retry to start mplayer it will find the stream
eventually (it may take 1-5 attempts) and when the sound is synchronized
and you don't stress the cpu on the system you can watch the dvb-t
stream without problems for hours.

I was hoping some special command options where needed to fix the issues
and somebody would know them.

The distortion is that the sound is so distorted you can't make anything
useful of it, but after stopping the stream wait a bit and then resume
the stream it is fixed.

Kind regards,

Jelle
