I've been having this issue with burning a video dvd using Toast Titanium (7.1.2). I'll put about 5 or so shows on a dvd and tell it to burn, after which it will start to convert the items, then when I come back about 2 hours or so later toast has either: a) Stopped doing anything (not frozen, just idle), or; b) Quit. Not quit unexpectedly (no message pops up), it's just gone. The thing is I've done this exact thing before and it's worked fine up until now. I was reading this thread wondering if maybe .avi is the issue, but the files I had burned before were in .avi too and they burned fine. Help!
