For those of you who, like me use Toast to burn you're copied and processed commerical DVD "backups", a word of advice...don't upgrade to Toast 6. I have found it will not burn DVD videos I have processed with DVD2OneX. Toast 6 invariably thinks what I am trying to burn is too big. I was relieved is wasn't a Panther problem. As it will burn and run data dvd's, the kind that run on your computer, but not in a regular DVD player. So until there's a fix, don't waste your money.
