DVD no longer reads dvds (searched the forum, no luck)

Recently I was mucking with ide-scsi for my burner (setting it up) and I noticed that afterwards my dvd drive would no longer mount or play dvds (any dvd).

Relevant information:

Any help would be greatly appreciated

your dvd is now a scsi device. Remap your /dev/dvd symlink to the new device and it'll work.

/dev/hdd (the dvd drive) is currently using the ide-cd driver and not ide-scsi (scsi emulation). Just to be sure:

chris@onizuka:~$ cat /proc/ide/hdc/driver && cat /proc/ide/hdc/model
ide-scsi version 0.9
CW058D ATAPI CD-R/RW

chris@onizuka:~$ sudo cat /proc/ide/hdd/driver && cat /proc/ide/hdd/model
ide-cdrom version 4.59
BDV 108A DVDROM

So /dev/hdc (my burner) is using the ide-scsi driver, while /dev/hdd (my dvd) is using ide-cd. So my dvd is still an ide device

You should keep them on the same driver. you'll have problems exactly like what you've got if they're different.

Anyways, the drivers can work independently without issue as shown (I placed a NWN cd into /dev/hdd, my dvd):

chris@onizuka:/dev$ sudo mount /dev/hdd /cdrom
mount: block device /dev/hdd is write-protected, mounting read-only

chris@onizuka:/dev$ ls /cdrom/
AUTORUN.INF               Setup.exe     data1.hdr    nwn.ico
ArcadeInstallNWN109.exe   Setup.ini     data2.cab    readme.txt
DirectX                   ar505enu.exe  ereg         setup.bmp
EULA.txt                  autorun.exe   extras       setup.inx
Online Install Guide.doc  data          ikernel.ex_  vssver.scc
Online Install Guide.txt  data1.cab     layout.bin

So the ide-cd driver is working perfectly for the drive, the exception being that it can't read dvds. This driver setup is also the same one I've had in the past, so I'm positive this isn't an issue of the two drivers conflicting.

ps: I saw your reply before you editted it,

Im having the same error No Medium Found, I didn't have it before I installed XINE or MPlayer. Anyone think it could beone of the packages fault ie libdvdread or libdvdcss?

This problem beats me.
