Kernel errors reading DVD

[Colin Paul Adams]

On two separate machines (both running Fedora 9) VLC fails when trying
to play DVDs, complaining of kernel errors trying to read a particular
sector (and just repeats - it is very hard to actually stop - in one
case i had to reboot the machine).

Aug 10 07:35:02 susannah kernel: end_request: I/O error, dev sr0, sector 4851460

My SONY VAIO laptop, running Windows XP plays it without a problem.

What can I do?
