The thumbnail pictures may not display if the digital camera is set to either Picture Transfer Protocol (PTP) or Media Transfer Protocol (MTP) when transferring video and still images to a computer. Some models of Blu-ray Disc player, Network Media player, A/V receiver and Home Theater system do not support either of these protocols.
It is recommend to set the USB Connection option on the camera to Auto or Mass Storage/MSC setting, if applicable. A USB card reader that supports the memory card of the camera can also be used.
