pinnacle 72e ultimate edition random crash

I am watching tv on ubuntu jaunty with the pinnacle 72e dvb stick ultimate edition.
This works fine except for the random crashes that occur, I've tested it with gxine
and klear. Sometimes sound disappears and after a couple of seconds the image freezes.
The only solution than is to restart the application and everything works fine again.
This freezes are random, I can watch tv for multiple hours without any problem but it's
also possible that it freezes every ten minutes.
These seem unrelated to anything else.
I first filed this bug against gxine, but because it is probably a driver issue I filed it again
here, I hope this is the correct package.

Thanks
