Nero burning rom error?

Just installed nero Seems to work fine, except for one thing . . . when I want to copy a DVD using the disk copy feature (on-the-fly), Nero doesn’t recognise (read) the source disk in my f drive for copying. Nero says that there is no disk in the drive! The disks I want to copy are ones I’ve burned, with no problems, with previous versions of Nero 6.

The weird thing is that Nero WILL recognise (read) commercial disks in my f drive (source disk for copying), but not my DVD-Rs. I had no problem with prior versions on Nero 6 copying my burned disks which were originally burned using Nero 5 or 6. Has anyone else yet experienced this error?

Thanks . . .

I have the same problem. :a
