> but I've wondered if their DVD's are "locked" somehow to prevent people copying them.
AFAIK there's nothing special about Netflix DVDs, although I've never stuck one in the Mac and tried to mess with it.
Most commercial DVDs are already "locked" so to speak with CSS encryption, although this was defeated years ago and the source code for decoding a CSS-encoded disc is easily available despite the efforts of the movie industry. Moreover, they will likely be region encoded as well, although since you're renting from a USA distributor and playing it on a USA DVD player (both Region 1) this should not present you with a problem.
To actually get the video from a DVD, you need to do two things: 1) decrypt the disc into its component .VOB and .IFO files 2) find an MPEG-2 component to allow you to export the video to another format to edit it.
A tool called a 'ripper' will do the first part, and make a copy of the component files to your hard disc, decrypted and (depending on the program) region-free. The movie industry claims rippers are illegal, and they may well be under the DMCA, but as far as I'm concerned, a ripper constitutes fair use since there are certain of my rare DVDs I have no intention of ever taking them out of the box again once I've imaged and made a copy of them. I don't use Windows, but they're out there. For the Mac, a program called DVD Backup X will do the job, and very seamlessly.
Second, you need a component to play back MPEG-2 video (and convert it to whatever your editing suite uses). If you use QuickTime, Apple makes a component (and I think there is a Windows version) that allows you to play .VOB files (the files you get off the DVD) in QuickTime, and then export it. This works great for the video -- not so good for the audio, since the component doesn't support AC3 "Dolby Digital" encoding, and a lot of DVDs are encoded that way -- but if you need just the picture component, this should work. The downside is that the component is $20, and you need QuickTime 6 Pro to use it (another $30), but this is a lot cheaper than some MPEG-2 decoders. There may even be free ones for Windows, but I don't know where (or what they are capable of).
Hope this helps.
