|I would try the DVD on another DVD player (not another computer). This may help narrow down the culprit. There may be compatibility issues between the DVD player and the DVD disc. If it plays fine on another DVD player, then we can assume your DVD player is the culprit. If it doesn't play on other DVD player then it's probably the DVD; maybe the method in which you burned the DVD.|
How did you burn the movies? Did you burn them as simple data files? If so, your DVD player may not read the movies correctly.
