it's meant to work fine using the stanard already-on-your-system-even-though-you-didn't-know-it bttv drivers
apparently, a workaround to manually configure the card for you if yast or kudzu or whatever doesn't pick it up right is to manually edit your /etc/modules.conf file to include...
alias char-major-81 videodev
alias char-major-81-0 bttv
options bttv card=10 tuner=2
options tuner type=2
as for software, i recommend xawtv, it's really simple to use and works really well, and is very standard as far as distro's go.
capturing... well the main one is 'vcr' which is pretty basic, but does a very good job.
