It sounds like poor quality on the burned DVD. That could be the type of media, dirt, the burner, the player in question. You need to rule out each, one at time.
1) Find another player to try it in. I have 3. The two cheapo's play anything the "good" one is finicky with burned media.
2) Play a DVD burned on another computer on your player that is having problems.
3) Try a different brand of DVD blank. Check out cdfreaks.com for recommendations.
Lastly it could be some form of copy protection if this is a copy of a commercial DVD. They are doing ugly things to the DVD images and menus on the originals to confuse copying. A PC playback program may be smart enough to ignore the intentional damage but a home entertainment DVD won't be as smart.
4) Try different ripping software.
