Simple "First Play" DVD problem

I just created a simple "First Play" DVD in DVD SP. I imported assets from Compressor (DVD Fastest Encode 90 Min) right clicked on the Track and selected "First Play". I burned the DVD...simple. When I played the DVD, after the video was finished, it started again from the beginning. According to the progress bar in DVD Player, the DVD was only half way through...so it did not jump back to the start...it appears that it layer down a second copy of the video onto the DVD so they play back to back. Any ideas of how to fix this in DVD SP? I looked at a Track setting just under the name called "end jump"...i assume this directs the DVD where to go after the video is done playing. It is set on "not set"...when i tried to change, I was unable and could not select any options here... I assume because there is only 1 track and no other options.
Any help would be greatly appreciated.
Thanks,

Dan
