I cannot for the life of me figure out what is happening to my videos! I take video that saves to an SD card. I upload them onto the hard drive, with "avi" extension. They play back perfectly in Windows Media Player. When I use Windows Movie Maker, they upload fine...editing is a breeze and playback is fine. Once I publish the movie, with extension "mp4" or "wmv" the playback is horrible. Complete distortion. I have tried changing the aspect ratio and this did not help. Even when viewing these on a tv it does not work. Please advise.
