I have a BDP7600/05 with 1.42 firmware, serial number KX1A1111446574. It's connected by cable to my router. It can see the music and video files on my PC but fails to play any MP3, MKV, AVI or TS file - "unsupported format" is the error message. Annoyingly it also takes minutes to finally display this message.

I have set up my Windows 7 PC as a DLNA server using first Windows Media player and then Mezzmo, but to no avail. Has anybody succeeded in playing streamed files?
