I just got done watching a DVD movie on my puppy linux lucid 5.2.8 and I wanted to watch another and tryed it a couple times and it says this "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.
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."

I tryed all types of players.

i go to /dev and try to find /dev/dvd or /dev/cdrom and they are there but the icon is a tryangle with a big ! in the middle. win i click it it says "File doesn't exist, or I can't access it: /dev/dvd"

so I looked for /dev/sr0. and it is nowhere. /dev/sr1 through /dev/sr3 is there but no /dev/sr0.

I dont know wat happend i watched a movie and tryed to watch an other one and play a audio CD and this happend.

/dev/dvd and /dev/cdrom just are simlinks to the real device. An exclaim in triangle means that simlinks are broken (because real device is missing or its name is changed).
Look in /proc/sys/dev/cdrom/info, determine a real device then create a simlink to the real device.

ln -s /path/file /path/simlink
For example, if your real device is /dev/sr0 :
rm /dev/cdrom (remove broken simlink)
ln -s /dev/sr0 /dev/cdrom (create new simlink)
or with single command:
ln -s -f /dev/sr0 /dev/cdrom (remove broken simlink then create new)

Is this a frugal install? If so, go to the folder /initrd/pup_ro2/dev.

Locate the file sr0.

Open another window to /dev.

Drag the file from the first window to the second.

In that case, get out your Puppy CD and mount it.

Click on the sfs file to mount it.

Go to its /dev folder and drag the sr0 file to your main /dev.

You could try this:
Code:
mknod /dev/sr0 b 11 0

Out of curiosity I have deleted and recreated sr0 this way.
