DVD Playback problems


Hey guys, heres the problem. (and it's not the choppy-playback problem)

I am running suse 9.2 on my laptop, and have not been able to play dvds. I have gotten rid of the suse Xine version, and got mplayer as well as the libdvd stuff. I should be fine to play dvds. The problem is, I don't think my pc is finding the dvd at all. I got the 2.6.11.2 kernel instead of the suse kernel, and it still doesn't work. I play the dvd in mplayer and it says: "Could not open DVD device /dev/hdc" (I specified /dev/hdc, and have tried many others only to get the same problem) I have tried to mount the disk [monut /dev/hdc /mnt/cdrom, Error: no medium found]

Dmesg | grep DVD reveals a CD burned drive, and the same drive, showing DVD capabilities listed both under hdc.

Any ideas of what to do?

Could be a permission problem As a test, run mplayer as su or root. If it works, set the permissions of the drive to 660 or 666. Though you may need to compile and install dvdread for xine to read DVD discs.

ok, you say you're "trying others". does that mean like /dev/hdd, /dev/hde, /dev/hdz ? that dmesg command should have listed the device name there...

the main thought is that this si a dwd/cdrw? in which case i would assume that it is using ide-scsi emulation for the cdrw side of things. as such it would be a device like /dev/sdc (if someone can clarify the name pls...) as it's pretending it is a scsi drive. i don't know what kernel suse 9.2 ships with, but if you are on a 2.6 kernel (run "uname -r" to see) then you won't need that emulation, and you can remove the reference to it in /etc/lilo.conf or /boot/grub/grub.conf depending on which bootlaoder you're using.

that being said, it mightn't be ide-scsi issues... i reckon it is though.

By "trying others" yes, I do mean /dev/ hda/hdc/etc....
Under dmesg it says hdc, so I have been sticking to that.
While I will try it under su again, I have done that in the past to no avail.

SCSI to IDE emulation is /dev/scd0....255.

Check if you have a symbolic link of /dev/dvd that is pointing to the real device. If you are using devfsd, it has to be the devfsd path not /dev/hdc.../dev/hdz.

Well, I check my /dev directory and learned something: /dev/dvd is linked to dvd:/

Now, when I ls -n dvd:/ , it says there are too many symbolic links and can't follow it. I get this error when I boot also. Note, I used subfs for the longest time - and ditched it when I upgraded my kernel. (DVD never worked, no matter the kernel)
