F14/KDE

Trying to play Video DVD on Two different Netbooks with Two different external USB DVD drives.

Two different Video DVD's and I get the Same Error message;

Playback failure:
DVDRead could not open the disc "/dev/dvd".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/dvd'. Check the log for details.

Tried the Mplayer and Xine and have the same problems.

Both Netbooks have played the same DVD's about a week ago ,but not now.

Both video DVD's will play without any Errors on standard Laptop with a CD/DVD drive internally, With Fedora 14.

boot your system then plug in then plug in the usb dvd then open a console and type dmesg see where the sr0, sr1,etc is being loaded. your system should be mounting the device in the /media folder.
also after plugging it in type lsusb and you should see the hardware. for some reason it is not making the link /dev/srX /media/dvd or cdrom etc.
please make sure user has plugdev and and audio and video in there group

What command would I do to check this ? :

"please make sure user has plugdev and and audio and video in there group"


lsusb

what happens when you are logged in as root.
in kde it is in user manager I use only the old cento's and it is different from FC14.
But vanilla kde. it is in Kmenu settings or kmenu >applications > system > user-manger. select the user add the the privileges to there groups. needed.
and another thing you do know that FC14 default install does not have the programs to play video dvd. You will have to install other third party linux software gstreamer good, bad, and ugly ffmpeg make sure you have libdvdread. The read out is a HAL program that allows you to use hardware devices per permission.

VLC, xine won't play in root.

In User Manager in Properties > Group Users > Select the users to join this group:

The User Michael is checked

There is other users that are not checked :

dbus
ftp
games
haldaemon
ssh

and many more are not checked only user michael is.

Is this what you were referring to ?

I guess you need to stop hal and try to mount the drive. you have tried cdroms and dvd. let me know.

Solved !

The problem was that if you don't have a USB External CD/DVD drive connected to a Mini-Netbook when doing a Fedora install VLC will set by default a DVD to DVD=/dev/dvd instead of DVD=/dev/sr0 and just MAYBE it will play a Video DVD. But 90% of time it won't

By having a USB External connected to your Mini-Netbook during the Fedora install VLC will be auto detected as DVD=/dev/sr0 .

I check both my PC and full size Laptop that already had a CD/DVD connected and VLC was set to to DVD=/dev/sr0 .

On the Mini-Netbook, I had to make the below changes.

In ~.config/vlc/vlcrc the settings are;

In section: #DVD device (string)
#dvd=/dev/dvd

and I edited as follows:
# DVD device (string)
#dvd=/dev/dvd
dvd=/dev/sr0


Now I can play Videos first and every time.

I would imagine if I were to use Mplayer or Xine I would have to find and make settings to DVD=/dev/sr0 because I didn't have the External CD/DVD connected at time of Fedora install.

cool I had that problem back in 2004 with Slackware 10.2 on the 2.4 kernel and the new 2.6 kernel that just came out. seems it is in the scripts.
mark it solved
