Same problem here, I upgraded to FC7 from FC6 and now I am having problems with my PV-149 card, it is a BT878 with 4 inputs and 4 chips, capable of 120 fps....theoretically.  Anyways, there must be some problem in the identification of the card and the BT878 drivers or......what else could it be?

Hi all,

I upgraded from FC6 to Fedora 7, and my Linux Media Labs LMLBT4M card
has stopped functioning (I get solid green output - but the webcams work
OK). Can someone suggest what the problem might be? Logs + modprobe.conf
