Has anyone created a dvd-r that worked fine on one player and choppy and pixelated on another?

I've noticed that most of dvd-r disks work fine on 3 of my dvd players but not on one. The dvd player I am talking about is the portable Panasonic DVD-LV50. What happens is that the movie would play fine up until half way through then it would start getting choppy and pixelated and then halts.

This doesn't happen to store bought dvd movies, only home made. I am using Ulead's DVD Workshop to author, I'm worrying if the software is causing the problem. I'm also using Pioneer's A03 to burn the disks.

I also noticed that after cutting the player off for a short period of time the video would play fine even from the same point where the problem occured. Yet further down in the video it would start again.

If anyone has any suggestions, I would appreciate it.
