Have an issue with a PPC running leopard 10.5, if I insert a blank DVD it will recognize the disc and ask how you want to use it or ignore it. If I have Toast running version 10.0.8 it sounds as if the disc is being written too, and then kicks the disc out of the computer? anyone else or anyone have this isssue. The disc's were working up till now, have used 50 of the hundred when the issue started. Have no issue's burning CD's. DVD's are Verbatim brand.
