Simple Q about my CD-RW/DVD Combo drive

[Atealtha]

I got a samsung CD-RW/DVD combo drive

It detects it as a CD-RW, but not as a DVD. how do I do that?

[bwkaz]

Put a DVD in and try to play it?

I don't know, that's what I'd do. It's not a DVD writer drive, right? If not, it shouldn't matter. DVD drives shouldn't be recognized any differently on the kernel side (at least, not from what I understand); the only difference is that they can hold more data. Just make sure that if your DVD is CSS-encrypted, that you have a library that can decrypt CSS (and no, none of those libraries are technically legal, but that's because nobody that wants to can actually make a DVD decryption program for Linux -- they'd want to release it open-source, but the DVD Nazis won't let any of their "secrets" (the 48-bit encryption keys) out into public knowledge).

Have you tried to use it as a DVD player? It's possible it isn't listing it as such but a media program (ie: mplayer) will be able to use the DVD option if you point it at your drive.

hey heres an update. I'm using xine, and when I press the DVD button on my ui, it reads for a tiny bit then shuts off. once it got as far as showing the FBI Warning on my Simpsons DVD.

I pointed to both /dev/cdrom and /dev/hdc

why is it closing so much?

[Atealtha]

also I have another Q (shameless bump). It reads my DVD, but when I pop in my CD into the drive, goto /mnt/cdrom, and type ls, I get nothing shown. Any ideas? I looked around here and got nothing

Did you mount the CDROM first?

[Atealtha]

I did mount /dev/cdroms/cdrom0, ran xine and got this with my Simpsons DVD

I'm thinking the bolded part is what needs to be fixed. Any suggestions?
