Live TV freezes

[hype]

Hi,

I got a new problem.
After watching live tv for about 5 minutes it just freezes.
If I switch to another channel, it runs again for about 1 minute.
Then I switch again and it freezes again.

Any ideas on this?
I attached the logs.

Unfortunately I cant see any sign of obvious problems in the logs. I'm not familiar with the Cinergy devices though, so I'm not sure if they're well behaved or not.
