System hangs when mounting DVDs

[Juan Casanova Rodriguez]

Hi,

Recently I am having problems with my DVD.

When I put some DVDs (not all) in my DVD reader systems hangs completely
(no capslock, no ctrl+alt+Fx no ctrl+alt+backspace)

This also happens when the same dvd is in the drive when I start the pc.

I burn some dvds with big files (more than 2GB) and K3b shown me a
warning about that. I didn't care so much and burnt the DVD. But I am
not sure that this is the problem.

Maybe the hanging DVDs are written in a different filesystem...

Any clues?

Thanks,
