Aw2000 supports 7 image file types, BMP, JPG,PCX, PNG, TGA, TIF, PSD. The list is in the help files in Images | Managing images.
Now you are thinking along some of the same lines I am thinking. And what if the video clips were saved in one of the supported file types, The individual video clips added to Aw2k. The video code added into the Listing template. The URL would be written already and uploaded as well. The individual images would be displayed in both the image spaces and display as a video clip as well. It might work. I am going to try it. All it can do is not work
