I am using version 820a of TV Suite V6 Beta. I can load two hour long Tivo videos and I then can edit them, but after I successfully save the edited videos (MP4), the program will then hang up when I try to load another video, for editing. I have to start the program again, to be able to do any more with the program. I tried playing the edited file, before trying to load a new file in for editing, and this kept the program from hanging up. I am using Windows 10 with all the latest updates, and all of my drivers are also up to date.
