problems with DVD drive and playing dvd movies

[DimGR]

Hello

I just installed the dvd drive today. I used to have a cd rom instead of a dvd drive as master and a cd rw as slave. I took the cd rom out and put the dvd drive as master. I can mount the dvd drive just fine but it does not play the dvd cd.

i get these errors

uffer I/O error on device sr0, logical block 1655264
Buffer I/O error on device sr0, logical block 1655265
Buffer I/O error on device sr0, logical block 1655264

this is my fstab

cdrom is now the dvd.

What kernel are you booting? uname -r

If it's 2.6.* then you don't need scsi emulation and if you're not using scsi emu then /dev/sr0 and /dev/sr1 are losers. You need the actual device name. It sounds like you have the dvd drive as Secondary Master which is /dev/hdc.

i am with kernel 2.6.6. and my CD drives ONLY work with scsi emulation. DO not ask me why..i do not know

Well you can try mount /dev/hdc /cdrom

You're not by chance mounting the drive and then trying to play the dvd are you? No need to mount the drive to play dvd's.

What does cdrecord -scanbus say?

I don't believe you. Remove scsi emu from your boot loader. Make sure /dev/cdrom and/or /dev/dvd is linked to /dev/hdc. Then you should have easy access to your drives.

For the record I have no idea what your error means!

How did you get it to work? I'm having same problem. I can mount the drive but cannot play a dvd. Just comes out as files. Here is what I get when i cdrecord -scanbus:
