I have an issue with a current shipment. I work for design company that specializes in point of purchase displays, and we have a number of media players, or what is a pretty common picture frame that also does video. We have specified this player and supplied an SD card to be used to upload a video in the retail store. I was called by the customer and told that the SD card won't play in the player. I have tried everything and the customer is right. The card is a 128mb card, it is recognized in every device I can find, camera, PC, SD to USB reader, but not the media player. The player reads every other SD card, but not this one. What could be causing this issue? I have reformatted the card, and I'm using the exact same video from the working cards. I have also used a 32mb card to rule out minimum limitations. I have a shipment of players and cards that won't work, I need help!. I have racked my brain and figure out why the cards are read everywhere but that device...a device that reads the exact video from other SD cards.
