Urrgghh...
Whoever's working on that FAQ, how about adding this one? This is
definitely a PCI problem, as has already been noted. The typical
solution is to adjust the PCI latency in the BIOS - this works most of
the time.
If you feel up to a bit of hacking, you can also try find the occurence
of "BT848_GPIO_DMA_CTL_PKTP_32" in bttv-driver.c . Change the "32" to
"16", or "8" to make teh Bt8x8 more agressive in aquiring PCI bandwidth
- will slow the system down, but get you better video...
