Hi Michael,

unfortunately, there is no complete "definitely true" answer to your
question. Different ppl on this list reported different behaviours with
their setups.

1.) Two or more DVB-cards share the same IRQ:
I've never heard of a setup like this that runs without problems.

2.) A DVB-card shares it's IRQ with some other periferal:
Some ppl on this list get this to work. However, with my own setup it does
not work this way. Once I tried to share the IRQ of the onboard VGA of my
ASUS CUA with one of my two DVB-cards: no success :-(

3.) A different IRQ for each of the DVB-cards
This seems to be the 'save' way to do it. I've never heard about
IRQ-problems with this setup.

Greetings
Christian
