There is generally no harm in loading kernel modules for experimentation.

For example, in your case it would be fine to:

# modprobe bttv
# dmesg | tail -20

and see if the driver finds the device.
If not, try the other ones.

Its easy to spot when a driver recognizes a device.  If it does not, 
dmesg simply says driver loaded.

If the driver does list information about the device, then you need to 
make an appropriate entry in /etc/modprobe.conf to make sure it comes up 
properly on future reboots.
