Just mount the DVD, authenticate, go to VIDEOS_TS (or something, can't remember exactly anymore) and DeCSS the .VOB files individually. VCDs are a little different. They don't have filesystems on the CD directly, rather the MPEG1 streams are stored like audio tracks on the CD. You have to rip them like Audio CDs to get the MPEG1 data. VCDgear (in the ports) will convert the ripped tracks to regular playable MPEG1 streams and back. > Also there are some CD-Rs which I could mount on linux or windows but > can't on FreeBSD; I think it's because they're multisession CDs which > don't start on sector zero, but I'm not sure.

Havn't seen any of these myself. I try to avoid creating multisession disks if I can, because they seem to cause a lot of problems all around. If you have a disk where this is reproducable, I bet the ATAPI and ISO9660 maintainers would like to see it (filed in your bug report). > And what about "multimedia audio CDs" (or whatever they're called)?

The audio > plays fine. I've only seen one of these. It had a regular filesystem on it that I was able to mount and view the (crappy cinepack encoded) AVIs off of directly. The audio tracks started at track 2 IIRC. I think there were at least 3 different kinds of "multimedia" music CDs however, so this is definatly not a complete answer. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
