Michael & Don,
I have not created any DVD's with the RCA. But, you can record in a DVD Quality or Regular setting. And, it does comes with a plugin to watch them on your TV (the quality is surprising good). So, I don't see any reason why you cannot create a DVD with that same file, do you? But when I can get around to it - it's a short summer here

- I've got a bunch of clips that I want to put to DVD, and will report back.
I haven't used the Flip video. But I first heard about it, and watched a very positive testimonial about it from Mike Stewart (Aka the Internet Audio & Video Guy). And you might want to check with his site.
I would also recommend to anybody who's interested to sit down and spend a good 3-4 hours with Windows Movie Maker. Because it is also pretty amazing what you can do with these little clips in terms of editing and effect. Like pausing your video clip frame by frame and saving an individual frame to make a separate photo (jpeg). Which you can also edit with another free program (GIMP) to add most any expensive Photoshop type effect.
Cheers,
Rod
