So I've got a Toshiba Qosmio G30, which has HD-DVD capabilities. Unfortunately, the CD drive (HD-DVD/DVD/CD etc) does not recognize anything I put into it. Note, I am using Ubuntu 6.0.1 (not the latest release, but the one before it). No data CDs, audio CDs, DVDs, and most likely wouldn't recognize HD-DVDs, although that I've not tried as of yet.

So what drivers do I need, or whatever? How can I get DVDs to play in my machine, etc?
