Yes it is. 1X on a CD is 172KB/s, 1X on a DVD is 1385KB/s. So 8X DVD is equivalent to around 64X CD writing. It still takes longer to write a DVD than a CD on most drives, but nowhere near seven times as long. -- Neil Bothwick Nymphomania-- an illness you hear about but never encounter. signature.asc Description: PGP signature

There is nothing special about a DVD ISO. Just make an ISO 9660-compatible image with whatever data you want (in fact, neither a DVD nor CD needs to contain a ISO 9660 file system at all). I usually do something very similar to: mkisofs -o dvdimage.iso -J -r datadir/ Then you can burn this "pre-mastered" image using (see growisofs man page): growisofs -dvd-compat -Z /dev/dvd=dvdimage.iso This should be roughly equivalent to: growisofs -dvd-compat -Z /dev/dvd -J -r datadir/ - -- Michael Kjörling, [EMAIL PROTECTED] - http://michael.kjorling.com/ * ASCII Ribbon Campaign: Against HTML Mail, Proprietary Attachments * * .

[gentoo-user] Generate data dvd iso image with growisofs or other
I'm having trouble digging out of google and growisofs --help how to create a dvd data image. growisofs --help give very little to work with but the reference to mkisofs lead me to man mkisofs where I find out how to make a video dvd but still not clear what cmdline is required for data dvd. Anyone here know a cmdline for creating a data dvd iso image on disk? -- gentoo-user@gentoo.org mailing list
