kworld is the "capture card/pc route."
that's why it's cheap.
this also means it's not as easy to use as standalone dvd-recorder.
but cheap card can yield higher quality video and you'll be able to pack more video per-dvd-disc than with dvd-recorder.
pick your poison; if you like to tinker with your pc, you'll go with card.
if not, then you'll buy standalone.
offcourse i agree that standalone is easier. it's same as vcr; hit rec, and you're set; with pc and the card it is never this easy.
