I have 3 Sony TV's - 22EX320 / 24EX320 and the 22EX533. I have all 3 networked over WiFi to a WD Live TV Hub where i store all my media files on the internal drive. I basically have MP4/h264 and MTS based video files. The WD is connect to my main TV and plays everyting i throw at it. Over DLNA i settled on mp4/h264 and m2ts as my formats as the Sony's support these. Also have a Sony Rx100 camera.

I have no issues playing all my video files (mp4/m2ts) over DLNA to the 22EX320 or 24EX320. But when it comes to the 22EX533 just about every MP4 file will not play - playback not available. The video format supported over DLNA is the same for all 3 TV's - So why don't the mp4 files work on the the 22EX533. I use Freemake video converter and Xmedia Recode if i need to create mp4 files - and they ALL play on the 22EX320 or 24EX320 - no issues.

I have tried countless programs to create mp4 files but not work on the 22EX320. Sony support were no help they could not tell why this happens - only said even thought mp4 supported not all files would play. Would not explain why works on the 22EX320 and 24EX320.

Anyone got any ideas ???
