DVD problems w/ Ubuntu

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
A few months back I Formated a HP Compaq dc5700 (small form) buisness
comp and
Installed Xubuntu on it, and this is my first experience with Linux. I
had issues with the cd/dvd right off the bat and posted about it a
while back. Well I got most of it working now. Took me 2 weeks to get
cd audio files and mp3 files to play. I cannot however get movies to
play yet. Well not all that is. I searched my but off and most what
was post was about having the correct library files for licensing and
plug-in files. I checked all that and as far as I can see It's all
there. Now I can a Documentary Movie to play perfect. "Generation
Zero" It's the original not a copy, but I can't get the Main stream
Movie DVD's to work. Says "could not read from resource" (Exaile).

I ran disktype and got this:

desktop:~$ sudo disktype /dev/dvd

--- /dev/dvd
Block device, size 7.194 GiB (7724113920 bytes)
CD-ROM, 1 track, CDDB disk ID 023BFD01
Track 1: Data track, 2.197 GiB (2358986752 bytes)
disktype: Data read failed at position 2358472704: Input/output error
  UDF file system
    Sector size 2048 bytes
    Volume name "TITANIC_SE_DISC1"
    UDF version 1.02
  ISO9660 file system
    Volume name "TITANIC_SE_DISC1"
    Data size 7.194 GiB (7724113920 bytes, 3771540 blocks of 2 KiB)
disktype: Data read failed at position 2358378496: Input/output error

If I can get past this I only have one more issue and I then I will be
done and happy. :-)

Do you know the DVD drive is definitely OK?

Do you get the same errors with other movies? What region are the movies
you trying view?

Also have tried other players, such as VLC?

Are all these audio and video issues something to do with being based in
the US? (I'm just guessing that's where you are, as I've never had a
problem with anything really apart from the odd codec, but I see a lot
posts about this.

As a side note, I've always found Linux Mint (based on Ubuntu) has far
better codec support 'out of the box'.

There is more than meets the eye, to a commercial DVD.

http://en.wikipedia.org/wiki/Compact_Disc_and_DVD_copy_protection

For each title that gives you trouble, use your search engine,
and see what protection method is being used. Some protection
methods allow a dedicated player to play the title, but cause
problems for computers.

In this case, it's possible they've corrupted the data structure
on purpose, to prevent file by file copying by computers.

Since this is Linux, you could "dd" and copy the entire disc
to make titanic.iso, then loopback mount the thing. But I doubt
that will change the data corruption issue. Whatever thing is
busted in there, will likely continue to be busted. If you copy the
DVD with "dd", you'd mount the resulting file something like this.
That allows a file to be treated as a block device and used
to represent a file system.

# Copy a DVD to a file, then loopback mount the file, and the DVD
# will appear in /media/mymountpoint. The "dd" command can only
# do a block level copy, until the file system says it hit the end.
# Check and make sure the titanic.iso file is big enough (7.194 GiB)

sudo dd if=/dev/sr0 of=titanic.iso

sudo mkdir /media/mymountpoint

sudo mount -t iso9660 titanic.iso /media/mymountpoint -o loop

Since I don't work with movies at all, I can't say what tool is
best for breaking the protection. In some cases, it may turn
out a tool is available in Windows, but not for Linux.

One other thing. If the "dd" command is failing, because it
thinks it ran into a bad sector, you can use the Diaz version
of ddrescue.

http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

I built and tested ddrescue for fun yesterday.

http://al.howardknight.net/msgid.cgi?STYPE=msgid&MSGI=%3Cikuh6t%24649%241%40news.eternal-september.org%3E

The source file is here. ./configure and then make, and you're done.

http://download.savannah.gnu.org/releases/ddrescue/ddrescue-1.15-pre1.tar.gz

Something like this, might "step over" a bad sector.

sudo ./ddrescue -n /dev/sr0 titanic.iso rescued.log

Yes. When I started the drive couldn't play anything at all.
Would not even show in the file system. Now I have .cda .mp3 (cdrom)
and most dvd.
I solved the cdrom mp3 issues by installing 4 or five mp3/muti-media
players until I hit the majic files(I'm assuming codec)
that bridged the gap. When I say solved I mean In the default media
player Exaile.
I did try installing a few more dvd apps but so far they are all
inherent to the same issue.

No.
I can play all burned windows media center dvd's, burned iso copies,
and some propitiatory DVD's (indy documentary type). The only thing I
can't play seems to be the "Hollywood Stuff". However, I'm sure a
burned copy would work.

Yes along with a few more that worked for others posting the same type
issues.

All the media I tried were produced, recorded and sold in U.S.

Yea, that's along the lines of what I was thinking. Something to do
with the extra protection found on mainstream movie dvd's.

But if windows can play it??? then why........???

Have you considered wrong(no) region code?
There should be software on the manufacturer site to switch
(a few times only) the region code......

It's to do with licensing laws AFAIK, which is a particular problem in
the US, or so I understand.

Have you installed the various packagaes for playing restricted formats?;

In particular this might help;

Thanks Foo That was it. All I had to do was DL that package and it
fixed not just that issue but my last remaining issue also. I now have
my first fully functional linux distro.
Should I kill the update manager now? Is It safe to take updates? lol

Sometimes the easiest solution is the fix you need :)  God knows how many
times I have been trying all manner of detailed fixes only to find the
fix was a common problem with the solution staring me in the face!

Sure, installing updates shouldn't break anything. Installing restricted
extras is made optional after, rather, than part of the OS install to get
around the licensing issues I think.

Re: DVD problems w/ Ubuntu

Well that was short lived. Now I have lost cdrom function .mp3/utf
volume, .cda. Not only that, but I decided to restart the machine to
see if that might clear it up and now I have also lost the system
tray, clock, basically the entire notification area. And no, there is
nothing there to right click on at the top or bottom of the screen to
restore it. I have been to every place that has the word settings on
it and there is no mention of the system tray or notification area on
anything. There "is" one setting I can't get to and that is xfce 4
settings manager/ Panel. Clicking on that is a dud. I searched and saw
one bug where the notification disappears when switching users, but I
didn't do that. I just restarted and logged back into the same user.
And yes, I did try shutting down a few times.

 I'm seriously thinking about ditching xubuntu and trying another
distro. It seams that in order to fix one thing you risk breaking
another. I was so hyped when I thought I had it all working. Now I
have more things "not" working than working. One thing is for certain.
Windows has nothing to fear from Linux as it currently stands.

Wow, I wouldn't have thought installing some codecs and things would have
caused those problems... Did you install any new video card drivers by
any chance?

To be honest I'm not to familiar with XFCE, but from memory I think it's
similar to Gnome? So it sounds like you have lost all the panels? Is the
desktop empty?

Not sure, but it's very possible because there was a section where
several files were deleted and replaced.

It contained several plugins including flash player so I at least have
you tube working now.

No I still have Home, File System, Trash icons and that's it. I have
to right click to get anything else.

So it sounds like you have no panels, or Taskbar to use a Windows terms?

Try Alt+F2 and enter "gnome-panel" to start it.

It says "no such file or directorory"

I think I'm going to try another distro and start over. I'll ask for
suggestions in a new thread.
Thanks everybody for your help.

Try to google for 'dvd decrypter linux ubuntu' and see if anything there
helps. Under Windows I simply run DVD Decrypter on protected regionalized
commercial DVDs and it has never failed to produce files which would play.
