I've bought a DVD burner :-) Should turn up next week sometime. I've been surfing around trying to get my head around how to set everything up, but I'm afraid I've been failing due to my limited number of active brain cells :-( Linux support for burning data DVDs seems to be nice n' easy, which is the primary objective, but I've been wondering whether I can back up my DVD movies too. All I want to do is: * Read the DVD onto the hard disk * Burn it back onto DVD That seems to be quite simple if it's a single layer disk, as it's pretty much a straight copy. Dvdbackup looks promising on this front, but it doesn't support copying dual-layer (DVD-9) movies to two single-layer discs yet: http://dvd-create.sourceforge.net/dvdbackup-readme.html Other methods seem to centre around ripping it, extracting the video, extracting the audio, compressing both, recreating a DVD file structure and burning it back to DVD. Which seem like rather a lot of effort and also rather a shame at having to lower the quality when I really wouldn't mind spending 70p on an extra disc. Is my understanding of this correct? Does anybody know of any alternative approaches? Cheers, Jon
Burn-able DVD's are mostly DVD-5 (4.8gig) where as pressed ones are DVD-9 IIRC, thus you can't just pack a full DVD-9 disc onto a DVD-5. One method to get around this is to extract the audio/video and take out anything you don't want (e.g. Languages you don't require, you could always create multiple backups covering the different languages), there's no re-encoding so no quality is lost; but the disc produced won't be a 100% backup. The other method is to re-encode all the audio and video to sqeeze it onto the disc while losing some of the quality. I don't have a DVD burner myself (My windows using brother does, the above methods originally come from him ;)) so I don't know what tools you will need on linux.. But I'd guess DVD::RIP would allow you to rip the required video/audio streams, It might even be able to generate a burnable DVD image for you by now, but I haven't used DVD::RIP in ages, if not there are other tools out there that will create an image you can burn from the files DVD::RIP will dump (vobs etc). -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
