It turned out that the program was not reading certain video files. I downloaded the current free version of 365, and though it recognizes and plays all the files, now when I try to burn a disk it doesn.t work.
The "Authoring" starts quick enough, but by the time it gets to 31% it slows doen, and eventually i got the pop-up that said the burning had been stopped, while the Authoring was stuck at 44%.
I closed the program, restarted the computer, and tried again. Again, it started fast, then slowed, and it has been at 42% for almost an hour.
Am I missing something here?
