poor quality of dvb stream

Hello,

after some software updates the quality of my DVB-card
is rather poor. However I'm not sure whether this is
a transmission problem, a hardware problem or a software
problem. I have uploaded a sample ts-stream to
<ftp://upload.mplayerhq.hu/MPlayer/incoming/foobar.ts>.

Could someone have a look at this file, please? Is it
possible to tell from this file what's going wrong?


Ciao
Andreas
