Query: Beautiful picture, but major compatability issues

Love the picture quality of this frame, but the process of copying and viewing photos is an absolute nightmare. I'm a software developer, so this ain't user-error. I cannot, for the life of me, figure out why some photos just won't display! After 40-50 hours of troubleshooting, I'm ready to throw it out the window. But, alas, I keep trying. I just want to understand the rhyme/reason, and I'll follow the silly rules, I promise! The card-readers... especially if connecting the frame to your computer to transfer photos... are so incredibly buggy. I can see the photos right on the card through my PC! But for some reason, they just "don't show up" on the frame. Frustrating. And customer-service is worthless.I'd keep researching and find another frame if I hadn't already sunk so much time and money into this one. My recommendation -- don't buy it.If anyone has figured-out the secret to the above problems, please, please, please post them here!
