I've been burning a few .ISO files to DVDR today - thank god I decided to test them.

I've used NeroLinux to rip the burned DVDR to a new .ISO - it always fails about 80% through with a read error.

I experience the same issue using K3b however - so it's probably not a Nero specific problem.

Any suggestions as to what on earth might by wrong ?

The burner work perfectly under Windoze btw
