Re: playing DVDs from hard disk or CD


Thanks to all who answered. 

This dvd is not encrypted, so it is not a libdvdcss missing problem.

$ xine *.VOB

works, but is not quite perfect.

See below for more questions.

mmm. No. I just copied the files to hard disk using Windows and then
dumped them back on a CD using Nero. Nothing special. What does vobcopy
or dvdbackup do differently?

-dvd-compat? What's this?

mkisofs contains a -dvd-video option which seems to be relavant if I
wanted to write to an actual DVD.

I found growisofs which does take -dvd-compat, but again this seems to
be more relavant to burning actual dvds.

Ha! This *sort of* works.

It doesn't work from the CD:

$ mplayer -dvd-device /media/cdrecorder dvd://1
libdvdread: Attempting to use device /dev/hdc mounted on /media/cdrecorder for CSS authentication
Reading disc structure, please wait...
libdvdread: Can't open file VIDEO_TS.IFO.
Can't open VMG info!

But it *does* work if I first copy to my hard disk from the CD:

$ mkdir dvdtestfolder
$ cp -R /media/cdrecorder/* dvdtestfolder/
$ mplayer -dvd-device ~/dvdtestfolder dvd://1
Playing dvd://1.
libdvdread: Couldn't find device name.
Reading disc structure, please wait...

There are 4 titles on this DVD.
There are 3 chapters in this DVD title.
There are 1 angles in this DVD title.
DVD successfully opened.

So far my attempts to get it to play from the CD have been unsuccessful,
but this maybe is close enough.
