Thanks for the info. I was a bit worried about bandwidth but I figured not many cards are going to be streaming the full transport - certainly not all at once, anyway, so I think I'm safe there. The only analog capture cards I own are mpeg ones so that should be good.

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