Used DVD's on PC, now won't work on Home Recorder

Once used on my PC with NERO +RW discs won’t work on my Sony 510. Even after erasing the disc, the menus, Format etc stay unlit.

Has anyone else found this annoying problem, or better still a solution. When you put a new disc into the Sony it formats it, is it a specific file sytem it uses.


Try formatting the disc with your home recorder.
If that doesn’t work try a new, unused disc.
Some recorders will not recognize discs that were
formatted by other machines.
