I would have posted somewhere more specific to libdvdnav, but dvd-de...@lists.sourceforge.net appears to be dead now.
I have a DVD on my hard drive unpacked in the usual format (VIDEO_TS directory, etc.) and not in an ISO. If I play it back, like so, it works no problem.
$ mplayer -dvd-device . dvd://
If I burn it to disc (I am using a dual layer 8.5 GB, since it is a large film), libdvdnav appears to choke and I can't seem to play it back off of the disc
Playing dvd://2. libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.BUP failed libdvdread: Can't open file VIDEO_TS.BU. Can't open VMG info! No stream found to handle url dvd://2
Exiting... (End of file)
It's very strange because the disc is mounted as a regular iso9660 filesystem. If I perform an md5 checksum on the files on the disc and back on the hard drive, they match perfectly. If I play the individual files back off of the disc or on the hard drive, they play fine. e.g.
$ mplayer /media/dvd/VIDEO_TS/VTS_01_0.BUP
Any ideas?

Most likely that's not strange but the problem. DVDs need to have a UDF filesystem, and you probably burned it only with iso9660. And mounting it is pointless. Well, unless maybe if you give the actual path instead of the device name to -dvd-device, though I think that won't actually make a difference. _______________________________________________ MPlayer-users mailing list MPlayer-us...@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users

Hey Reimar. I think you might be right, but I have burned DVDs as regular iso9660 and had them playback on standalone vanilla DVD players without any trouble.
Nevertheless, I took your point and burned it again as UDF file system. Something interesting happened this time.
All the files (VIDEO_TS/*) burned correctly and with proper checksums, save one file, the last VOB (VTS_01_8.VOB) which did not burn properly.

They probably support both. I think there was once a patch for libdvd* to use both, but I don't know if it was applied or if it was how to select between them.

Na, that is around the end of the DVD. I'd guess the UDF file system structures may have pushed the size to be too large for DVD. Or you had just bad luck (I guess the chances for bad luck are quite a bit higher for the combination second layer/outer border of disk). _______________________________________________ MPlayer-users mailing list MPlayer-us...@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users

Interesting. I'd just like to see the disc be able to play on a standalone player, so the patch probably wouldn't be too useful for me anyways.

What do you suggest? I am burning to a dual layer DVD (8.4 GB) since that it is too big to fit on a regular single layer DVD.
