Magma cases, while having their own PCI bridge, still route through a

Which means, as long as you're not pushing the 133meg/second PCI limit
- you will be fine. A typical 40mbit full transponder is ~5meg/second,
so even with 4 cards tuning there shouldn't be a problem.
Note, this is only for DVB cards, when you're dealing with analog
capture (non-mpeg) boards sending uncompressed video, PCI bandwidth
gets used up real quick.
