content: I bought 2 DP-758.I tried to use my 4G SD card from my cell phone and my digital camera, but the DP-758 would not recognize it. I had to order older (slower?) 2G SD cards.After the DP=758 recognized them, they run through the slide-show a couple of times, then stop at the setup screen. The menu has nowhere to set it to continuous.The resolution isn't very sharp.When I call the help line I sit on hold, being told my position in the queue. Several minutes after being told I'm #1 in the queue, I am told to hang up and call back at a later time because all CSRs are busy helping other customers. This has happened TWICE! This is completely unacceptable.I have received substandard products and even worse customer service. I hope I'm not stuck with 2 unacceptable photo frames. Coby still hasn't responded to my email request (over 2 weeks).Spend your money on another frame from a different manufacturer.
