What to do with a DVD-RW +VR disk? UDF file system

On my Toshiba D-VR7KC2 DVD recorder I have recorded some video on a DVD-
RW, using the +VR recording format.
But I'm unable to play it on my wheezy system in either VLC or the Gnome
Mplayer.
Now according to online documentation I have a strong suspicion that this
is recorded in some form of the so-called UDF file system. What do I
have to do to get my machine to recognize this, either for playing it or
for copying the video off it?
Writing video to it would be nice, but not immediately needed.
I might add that I have no problem playing ordinary commercial DVDs.

Is the disc finalized? Can it play in another DVD video reader?

error, maybe it gives some clue about the failure.

UDF is quite well supported format for reading (and a bit less when it
comes to writing) so this wouldn't be an issue at all.

Opening vlc from the command line, and attempting to open /dev/dvd (the

for a device is a mystery to me. Anyway, now vlc is there you'll want to
go to the Disc device section from Media/Open Disc... and give it
something like /dev/cdrom or /dev/srX (x=1,2...),
The configuration file for vlc is in ~/.config or you could set a
default other than /dev/dvd in the Input & Codecs section of the
Preferences menu.

That's weird...
sm01@stt008:~$ ls -l /dev/dvd
lrwxrwxrwx 1 root root 3 sep 25 11:13 /dev/dvd -> sr0
Does the system detect the insertion of the DVD? I mean, can you see an
icon on the desktop or something under "/media/*"?
> But I did find a device /dev/video0.
Hum... this is usually for webcams or video cameras, not DVDs.
What's the out put of "ls -la /dev/video0" and "dmesg|grep -i dvd"?

I think the problem could be at DVD media detection, it seems not to be
recognized by the system.

Run lshw as root also.
I get this:
*-cdrom
description: DVD writer
product: CD/DVDW SH-W162Z
vendor: TSSTcorp
physical id: 0.0.0
bus info: scsi@1:0.0.0
logical name: /dev/cdrom
logical name: /dev/cdrw
logical name: /dev/dvd
logical name: /dev/dvdrw
logical name: /dev/scd0
logical name: /dev/sr0
version: TS00
capabilities: removable audio cd-r cd-rw dvd dvd-r
configuration: ansiversion=5 status=nodisc
If your system picks it up, from there it has to be configuration.
I've got the same problem. I've never had movies on a debian system,
but then again, I've never spent enough time to figure out why.
First steps so far, for me, was to go here:
put the right entry into /etc/apt/sources.list
update, download the key, then do a 'safe-upgrade' with aptitude.
I think the site is going to be my main resource because the forums
for SMplayer and Xine are woeful.
In a past experience, I never got an answer from the xine mail list
and there were maybe three messages on it over a one month period and
I posted a question on the SMplayer forum a week ago and still no
answer there.
Anything I pick up I'll post as I go.
Regards,
Weaver.

Possibly. Except that I have no trouble playing a commercial DVD, which
I presume not being in the cdrom group would also prevent. Nonetheless,
I'll put myself into the cdrom grop.

What's my next step? Presumably it's a permissions problem. What is the
meaning of user ID and group ID 4294967295 anyway? Should I copy the

Should I run vlc as root? Should I try to chmod the files on the DVD

Has it logged anything to /var/log/(something)?
Hmm, a quick search implies there might be a vlc-log.txt file somewhere.
Check your home directory.

I don't think it's permissions (you did log right out and in again after
adding yourself to the crdom group, right?)

Convert those values to Hex and you get FFFFFFFF (or -1). It's a dummy
value. Probably to avoid matching with any exisiting user/group IDs.

Try opening the VR_MOVIE.VRO file directly from VLC. Some searching

I doubt that will work.

top-level directory on the DVD has no permissions -- neither read, write,
nor execute are allowed to anybody, no matter whether owner, group, or
world.
Unless VLC partially runs as root, of course. or completely bypasss the

Hmm, very odd. Perhaps the umask= option on mount can override this?

prdinary user running gnome, I was told it couldn't mount it), then
copied the entire disk as files to my hard drive, then changed the owner
and permissions to my my files, with rwx permissions.
After that, I could get VLC to play the first mpeg in file., but none
of the others. It completely ignored the VR_MANGR.IFO file, which is
supposed to contain the menus and index the way mpegs are scattered
within the VR_MOVIE.VRO file.
I'd be at happy if I could figure out how to split up the VR_MOVIE.VRO
file into mpegs, so I could play them separately. Especially if I could
also extract the menu information and metadata in the VR_MANGR.IFO file.

need root because the top-level directory on my DVD has *no permissions
whatsoever*. The files within this directory, though, have reasonable
permissions for user, group, world. But the uid and gid are -1.
VLC will only play the first program in the files so copied.
To get the rest, I use a program I found at http://www.pixelbeat.org/docs/
DVD-VR/ which links to http://www.pixelbeat.org/programs/dvd-vr/
It reads the IFO and VRO files and puts together a sequence of VOB files.
VLC will play these VOB files.
I've used more disk space on my laptop this week than I've used in the
previous year, though -- essentially two copies of the data on the DVD.
It wold be good to find some way to combine all this hackery so as not to
need all that file space.

them, even being root when issuing the mount command, i still ended up
with the same no privileges on the root directory.
sshfsing in to root didn't work either -- apparently the sshfs client
rejects the attempt, and didn't even ask for a password.

VR/ that decodes .VRO files something that VLC (and other media players)
should do in a streaming style to avoid using all that temporary disk
space? Or should it be a file system that VLC just reads stuff from?
