Just got stupid and paid for the upgrade to Toast 16 Pro. Looks like there's a few new utilities and 1 new feature(the multi-cam feature) and it also looks like Corel Quality Control hasn't gotten any better. Running Mac OS X 10.12 Sierra. In the burning screen when you click on Menu, the drop down selections are transparent so their text is basically lost because of the background showing thru. The same thing on other dropdown menus. See the attached screenshots.
From what it seems to me, I paid for a new version that just has a different color scheme, 1 feature most people won't use, and User Interface bugs. I haven't really played with it to evaluate the burning performance but the one blu ray disk I did burn, never got better than 2x on a 6x Blu Ray on a 16x Blu Ray external drive.
Also, after I installed the "100 extra" themes for mydvd, there's no way to find them or use them.
I have chatted with Corel about this and they have sent the issues to the tech department. I'm not optimistic about getting any fixes due to their history of Ignoring Toast 15.
I hope they prove me wrong. If you have Toast 15... I would wait before throwing away your money on Toast16. Don't be stupid like me.
