Query: COMPLETELY WORTHLESS

This product is so defective it should be recalled. I can only display a maximum of 161 pictures, even if you have a 4GB SD card with over 1000 pictures, it will only display the first 161 pictures. Even though it has a USB port for USB flash drives, the interface does not even give you the option to read from a USB flash drive. There is also no "shuffle" function for the slide show feature.I spoke with White Westinghouse Tech Support, and they acknowledged that all the above things were known issues, but there was nothing they could do to fix them. I explained that no where does it mention that there is a maximum limit of 161 pictures!
