It seems like nothing related to Blu-ray works. I tried to make a Blu-ray disk from two different approx. 19GB .m2ts files. Both times the burn stalled at 99%. Not to be thwarted I tried to create an image file. This said that it reached 100% but did not actually finish.
I am very irritated with Roxio that they would release a piece of software that was simply non-functional.
