I have made a presentation which runs fine within the preview through the rise vision site, however when use my display device which is a MX MBOX media player dual core it runs slow when playing a text scroller or scrolling general text. It even runs slow when playing moving GIF images. However it starts off at a reasonable speed, but then after around 20-30 seconds it gets slower and slower until its just running at a constant slow speed. I have limited the amount of moving objects within the display. Now It has 4 GIF images, 5 static images and 5 text scrollers and other parts made up of static text.
