I have been using Sonic 6.1 for many years. I recently dedicated a new computer & 40" tv monitor to watch the MP4 Video's that I have recorded. If I burn the video's to a DVD I can watch them in a expanded view on my monitor. If I try to watch them as MP4 files using Sonic Cinne player I see only a square picture which does not fill out the screen. Is there a software upgrade to correct this or do I have to go to a newer version of Roxio Software.
