I have made a movie using the Flip Mino HD camcorder and the software that comes with the camera. When I exported the movie to an mpeg-4 file, the movie played perfectly and the sound and video was great. However, once I burned it onto a DVD-rom, it played choppy. Whenever I put the DVD into a computer's DVD drive, the movie skips, the sound cuts off, and it just is unwatchable. Why is this happening and how can I fix it? Also, the movie is 984 mb and 14 and a half minutes long. Thanks in advance!
