I have Popcorn and I have done latest update. I have video_ts files on my computer from my finalized camcorder DVD's and the MAC wont read them, so I purchases popcorn to convert the files to a readable format. I have tried to put the video_ts files in the player section of the program since I don't want to burn them at this time, and Popcorn will export up to 30%, it has never gotten past 30%. I have tried to convert my mpg to mp4 files and that worked. Can some one help me figure out what is going on?
