Not totally related, but I've had a good deal of trouble trying to
capture from more than one card (and display from one of the cards).
I don't get oopses or anything, but the system starts to choke as if
the PCI is totally overloaded. (720x480x30)
I think I saw some problems with data loss when I started the capture on
all four card's, at the same time. What I saw was on the last two cards
so was ther somtimes some green horisontal lines on the saved jpegs.
When I started the captures in serial then there was no green horisontal
lines and no opps as well.
But I have to do more tests to be sure that the oopses was not caused by
a badblock on the swap partition before I can continue the parallel
capture testing..

256MB? Then the other suggestion (that the oopses are due to a bad block
in swap) seems much more likely. Logically, if I can do 2x25fps with
128MB, you should be able to do 4x25fps with 256.
Swap is off at the moment it was about 512MB when I got the oopses,
I could try this: bttv card=100,100,100,100 gbuffers=2 but I will wait
until next week to se if the system is stable with the current
configuration and with only one card working at a time.
Thanks I will repport back later how it went.
Yes, please do.
