I don't know if anybody else is experiencing this, but since Aug 22 when Apple released OS X 10.10.5, Toast 14 will not burn blu ray or HD disks. The burned disks freeze, jiggle, and are unwatchable. I have been dealing with tech support for two days and they cannot fix the issue. They said to wait for an update. Nice. I use the program to create blu-ray DVDs for my work, and now I am out of business.
If you have Toast of any version, and OS X, do not update to 10.10.5 or you will regret it.
