Not sure if this is the correct forum, but I have an odd issue and I'm wondering if anyone has a solution. I put together a presentation in keynote, and took screenshots of everyslide and stuck them on a USB drive. When my friend plugs in the USB to the back of the TV's located in her offices, the JPEGs will play fine, but then it will show blank slides. It is a 19 slide (jpeg) presentation that will loop, but after the 19 jpegs, 19 black screens will scroll before restarting the loop. I thought maybe there were hidden files, so I reformatted each drive, yet we still have the problem. Any body have any clue how to accomplish this? The TV has the capability, as shown by being able to produce the 19 slides we want to show, but we're not sure what the issue is with the 19 blank screens that follow. This is a dental office, and none of the TV's are hooked up to computers or a network, just indiviual cable outlets. So running from a DVD or a hub of some sort isn't applicable. PS when I try this on my samsung TV, it just shows the slides and nothing else. Please let me know of any suggestions!
