I have just bought Toast 20 pro with the Blue Ray tool.I could not get it to instal on Venture Toast has come across a problem and has to close.I tried it on Big sur i got it installed on there.I only bought the pro version because i was under the impression i would be able play Blu Ray disks i own .Is it the case you can only burn Blu ray disks on there and not play them on here?.It seems daft ro me that you can record disks on there but not be able to play them on a Mac.I do have a Blu Ray player by the way.If i had known it could not play my Blue Ray disks on here i would have bought the basic version.All so it sometime to play a normal DVD with the bouncing ball.I had prevulrsly had Toast 17 which worked fine.
