Using MEP2015, burning DVD of finished project from hp windows PC. Making video project from various video sources that have types MP4, MOV, wmv. The MP4 picture fluctuates and jumps up and down all crazy with what looks like lighning bolts shooting what should be a crystal clear playback picture. The other formats play fine. I looked at the VTS._....VOB File on the computer that was created by the burn and it jumps too so the issue is Not with the DVD type or TV or anything else, it is in the encoded movie file prior to being burned to dvd. But the playback on the simulated TV menu display test that MEP provides prior to the burn plays everything perfectly! Prior to viewing these clips when creating the original project I had to activate different types of video files in order to view them, MP4 and MOV (is this what is referred to as codec, this is all new to me) and now the project appears to have a conflict with these types. Is there a simple solution to corect playback of finished project?
