What should i do for video capture.. ?

[OoteR02]

I'm trying to figure out which is the best option, i'm looking to dub videos to dvd's through encoding it on my computer.. Or should i totally go the other route and just buy a dvd/video dubber/recorder or whatever that would probably be faster, but far more expensive, especially since i want a new graffix card anyway. My gf3 ti 200 is aging very badly. :/

Any comments or suggestions are appreciated.
