> Latency? Is there some BIOS setting or how it can be changed? Sometimes you can set it in the bios for all slots, sometimes only a max value. AFAIK you can also set it individually for each grabber card using the respective v4l(2) driver, with an insmod parameter "latency". This should have a value in milliseconds between 1 and 255. The higher the latency, the longer a PCI bus master is allowed to grab and keep the PCI bus. This way maybe you could give your cards a bigger part of the bandwidth over the disk. OTOH now you might start having throughput problems to your disk controller :-( I am afraid it's insane anyway to run more than 1 grabber card on a PCI33 bus, for full size capturing. My previous motherboard (via 333 chipset) couldn't even keep up with 1 grabber card at full resolution...
