I've just started having issues making dvd's with toast. I open a saved project from my movies in Toast. Put in a blank dvd. Click the record button. It seems to be going alright but when it gets to "Filling the ram cache...100%" it just sits there and won't prompt me that it's done and to eject. I've tried repeatedly but it's always the same. It was working fine until now. What am I doing wrong?
