Well, My old vic-2.7 still works with the bt848 driver. Please make sure that you have : cd /dev ln -s meteor btkr ln -s meteor0 bktr0 If it still does not work please let me know. Also on http://www.freebsd.org/~ahasty/Bt848.html There is a version of grabber-meteor.cc for vic-2.8 which supports both the matrox and bt848 driver by basically locating /dev/bktr and /dev/meteor no other bt848 specific ioctl was added. Try 16bit color depth with fxtv and your X setup.
