There is some strange problem with bt848 hardware which means you can hang your PC while changing video mode. I could not find a suitable fix for the bt848 driver (except for adding the equivalent of sleep(2 seconds) all through the driver. Thie kenel option make card power up in PAL mode. The problem was that the default power up is NTSC mode and then you do a switch to PAL for your cameras. This bug took me ages to work out. I have a VideoLogic Captivator PCI card too.
