I purchased Toast DVD with the Bluray add-on ($19.95 + $15 for add-on) from the app store the other day and still after several tries Toast DVD will not complete a Burn to Bluray disc. Around 47% complete the Encoding GUI stopes updating. The app is still running. Selecting pause then Resume the complete jumps to 84%. Activity app shoe Toast DVD is using 2.4GB of memory and only 5.6% of cpu time. So I am really confused why this app is failing so bad. I have used Toast in the past and this has got to be the worst app they ever made. Don't waste your money.
