I still say the best way to capture video is with a standalone DVD recorder
that can be had for about $150.00 at Wallmart. The video will (usually) be in an MPEG 2 format that can be imported to the PC for editing if need be. But that's just my .02.
Here's a few more video editors free or cheap. I haven't tried any of them except Jahshaka, (I couldn't get it to work).

My copy of Showbiz 2 came bundled with an HP light scribe DVD burner. (If I remember correctly). I can't recommend the HP burner because mine crapped within a year of purchase, and HP didn't honor the one year warranty. But if your in the market for a DVD burner. And if you live near a Wallmart, I suppose you could always buy one, (check the box to see what, if any video editor, comes with it.) instal the editor, and try it out, if you don't like it, bring it back to Wallmart and get your money back. Keep your receipt, don't wait too long bringing it back. My copy of showbiz still works, even though the DVD burner is long gone.
Let us know how you make out. I'm interested on what you find, and what works for you.
