Hi. I have recently acquired two Panasonic LED edged LCD TV's. They are a TX-L37D25 & a TX-L37V20. Both have streaming functions & USB2 sockets for connecting WiFi adaptors. Both TV's have been successfully set up & connect to the Windows 8 PC & Windows Media Player. The anomaly is as follows: 1. Videos & pictures stream faultlessly. The TV's see all the video, picture & audio folders & anything can be selected using the remote control. However, MP3 or WMA format audio tracks can be chosen as normal but they will not play. The manual states that if a file format is incompatible, a message appears but this does not happen. Any advice is appreciated. Thank you.
