Unable to read DVDs

[chirag_gajjar]

I have a Sony combo drive that can read DVDs and write CDs. Previously it was working perfect but now it just doesn't read DVDs. It is working perfectly as cd burner and can read disks other than DVDs. I think the problem started after i reinstalled windowsXP with SP-2 but i m not sure. Please help me out.

Doesn't it just read DATA DVD's or Video DVD's?
Try using it from a linux live cd, and mounting a few dvd's from there.
That might help isolating the problem.
