Hi,
I'm running the latest Mezzmo (4.0.3.0) and have just purchased a Hitachi 32" HXT16U TV. It supports DLNA out of the box and everything was running OK until I came to try HD. It will happily play MKV files but there is no sound being sent with the video.

Mezzmo has picked the TV up as a Generic NTSC device.

Cheers
Paul
