Yes, it looks like it is using shared IRQ's. I have attached a cat /proc/interrupts.

No.

I have just tried out 1.7.5. It looks like it got a little bit better,
but it stil has not solved my problems.

I have tried playing back the stream from 127.0.0.1. The problems are the same.
So it has nothing to do with my network card. I will try to remove some of my DVB-Cards
