I am attempting to back up some video DVDs. Has anyone here successfully burned a large ISO to a dual-layer DVD? I have tried many programs, including growisofs and cdrecord, with no luck. What do you use? Can you give me a command line that will burn an ISO to dual-layer media under KnoppMyth?

I am attempting to burn DL DVD+Rs on a Dragon 2.0.

Thanks,

OK, after many false starts, I have a method for backing up video DVDs to dual-layer media. This page was most helpful:

I was able to back up a video DVD with only two commands:



where the directory at the end of the second command line was created by vobcopy in mirror mode (-m) when it copied the DVD.

The key for me was the -dvd-video option. If I left it out, the burn would fail, even with the -dvd-compat option. The -speed 1 option may also be important; people have reported failed burns without it.

I noticed some flakiness when trying to play the DVD immediately after burning it. For example, the DVD menus didn't work, and on the second try I lost all sound throughout MythTV. But I rebooted and the DVD then played fine, menus and all. I'm inclined to think this has to do with ongoing DVD autodetect wackiness on my system. Oh, well; something else to work on.

Yes.

growisofs

Just like the growisofs man page says:

Make sure the ISO filesystem is created in a dvd-player
compatible manner. (e.g. if using mkisofs, us -dvd-video)

That was my problem. I was reading the growisofs man page. What I needed to read was the mkisofs man page so I'd know about the -dvd-video option.

Thanks.

Yea, I made a few coasters before I figured that out.
