This has been happening without fail since I updated to Toast 10, so it happened with late versions of OS 10.5 and continues with 10.6
Toast will burn data, music, movies fine, but always quits just as its going to start verification. It means that my discs do tend to be fine, but I have no idea if they've burnt without errors. This is obviously particularly serious with data backups, but also mean I have to listen or watch through any audio or video discs to check they're OK.
I have tried reinstalling Toast several times, and I even had to do a complete system reinstall a few months ago, and the problem was there still.
Any ideas what the problem might be?
