Problem with dvd themes & Ashampoo DVD burning studio 8


I’ve been burning a few avi files onto dvd using my registered version of Ashampoo Burning Studio 8. My problem is that whenever I select a dvd theme from the dvd theme pack, it generates the same preview image of the movie in the background. the divx icon flickers in the the systray while the preview background is being created.
the preview clip is always the first second of the film as well.

I thought there would be different preview thumbnails generated. Any idea what’s going on?
