I bought the new Virtual Santa HD from Holiday Projections and also purchased one of the led projectors they sell. http://holidayprojection.com/led-projector-without-projection-effect-212-p.asp I have tried loading the mp4 files onto SD card and onto USB stick but when ever, I try to play them, the audio sounds smooth but the playback is very choppy and unusable. I downloaded a short home movie filmed on my iPhone in HD and it plays fine. Any ideas? Had anyone had success playing back the new Santa HD on one of these mini led projectors? edit: by the way, the files play smoothly on my Mac but I can't see any settings I can change on the projector's menus to correct the problem. There must be something I'm doing wrong but can't figure it out, esp since my home shot clips from the phone play fine. ???
