I've used Toast to burn DVD's for years and it works well. Some of their other features are problematic. I just tried to use their live screen capture program and it did not play well with Default Folder X. Integration between products (DiscCatalogMaker, Capture, MyDVD, Secure Burn, Audio Assistant, Slice, Titanium) is poor. They just seem to have slapped them together.
Support is fair. Representatives are not that knowledgeable, initially giving boilerplate answers to questions. They either don't bother to read the description of the problem or they don't understand it. But they do work the issue and follow through. This is better than for some other programs such as Bartender which completely ignore your requests. Usually after 2 or 3 iterations I decide it just isn't worth the time to work the issue. Rather than trying to fix the problems with Live Screen Capture (which likely were inherent in the poor program design) I just switched to Snapit.
It's on sale now for $69.
