DVD burned on Mandriva unreadable elsewhere. Why?!
I've got a Mandriva KDE desktop with DVD burner and an FC6(GNOME)/Windows laptop with a CD burner (and DVD player). To backup my FC6 data, I put everything on my Mandriva box in the hope that I'd be able to burn a backup DVD there. I've tried burning several DVDs (DVD-R, DVD+R, different brands of DVD, etc.). All of the DVDs are readable on the Mandriva box, none of them are readable on FC6 or any other computer for that matter, not even on Windows!
The burner I'm using is K3B and I did try different settings such as "do not allow multisession" and "use buffer", etc. No difference (the DVD player is in French, so I'm giving a rough translation here).
I'm anxious to backup my FC6 data so that I can do some spring cleaning as well as a fresh installation of FC7 next week, when it comes out.
