primary device: Hauppauge DVB-S
secondary device: Hauppauge Nexus-S
every card has its own IRQ

I've already tried 1.2.5.pre1-pre3 and nearly every version <1.2.5 with the 
same result. And I've tried 1.2.5pre2 without using masks for EIT-Filtering 
- also with the same result...
As it seems to be difficult to point out the piece of code which cause that
error, I've another idea:
Is it possible to check frequently, whether the second device is in a valid
state (i.e. receive no unknown picture type). If so, it would be possible to
find out, when the error occur the first time.  Do you think that's
possible?
Is it also possible to track the actions of the second device (channel
switching, received packets, ...)?
