I have been trying to use tvtime to watch tv on debian/fc5 system (kernel 2.6.15 loaded with bttv module 0.9.16.). I am using a PlayTv Pro2 PixelView PV-M4500 which uses the bt878 module.
kauv4:~# cat /etc/modprobe.d/bttv
install bttv /sbin/modprobe rtc; /sbin/modprobe --ignore-install bttv
options bttv card=37 tuner=5
kauv4:~# dmesg | grep bttv
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).

bttv0: PLL can sleep, using XTAL (28636363).
Since I dont have a cable connection at home, I am using a settop box's composite output to connect to the composite input of the tuner card. The problem is that eventhough I am getting a very good display of the tv, everything is in black and white.
In the TV input type I am using PAL-NC (note that Indian standards are Pal-BG, which is not in the list of availabe). I've tried connecting my video camera's composite output, but the display is always in black and white. There is no problem with the card since on windoze OS I am getting proper colour display.
