Try running dmesg and look for a verison message from bttv. It should look 
something like this:

Linux video capture interface: v0.01 ALPHA
i2c: initialized
bttv0: Brooktree Bt878 (rev 2) bus: 0, devfn: 120, irq: 15, memory: 0xfd5fe000.
bttv1: Brooktree Bt878 (rev 2) bus: 0, devfn: 128, irq: 11, memory: 0xfd5fc000.
bttv: 2 Bt8xx card(s) found.
bttv0: model: BT878(Hauppauge new (bt878))
i2c: bus registered: bt848-0
bttv1: Hauppauge eeprom: tuner=Philips FM1236 (2)
bttv1: model: BT878(Hauppauge new (bt878))
i2c: bus registered: bt848-1

The v0.01 ALPHA is a signal that it isn't the RedHat default kernel 
drivers. THey show up as something like:

Linux video capture interface: v1.00
bttv0: Brooktree Bt878 (rev 2) bus: 0, devfn: 136, irq: 9, memory: 0xf4001000.
PCI: Enabling bus mastering for device 00:88
bttv: 1 Bt8xx card(s) found.
bttv0: NO fader chip: TEA6300
bttv0: model: BT878(Hauppauge new)
