Not out of the woods yet!!

WTS...I'm following your suggestions.
I'm trying to put several small repeating thumbnail video clips on on a still background to be exported to REEL DVD. I'm using Premiere 6.5. In REEL DVD each thumbnail vid clip will be a button linking to a full screen full length video. So far I've been able to put the small clips onto a still background by using the "effect controls" window and selecting motion. I then set zoom to 20 percent and delay 100 percent. I also set the start and end points the same. Everything works fine. The only way I could find to make the clips repeat is to put several of the same clip on each video track. Five tracks total, 5 different clips, 4 clips per track.
The only problem might occur if the dvd user doesn't make a choice before the thumbnails stops playing. i could place more clips on each track and/or extend the length of each clip but thats wasting precious disc space and/or resolution. Is there a better way to do this that I'm not seeing.
