I just downloaded the latest version of mezzmo today after trying twonky and tversity. I am really liking this DLNA and would like to purchase it but I have 1 problem first. I have many mkv files and stream to xbox 360's around the house. Well avi's play great but when I select a mkv it starts goes black then takes me back out to select the video again. I do not even have time to pause and let it transcode or anything like that.

Any idea what is happening or something I can do to fix this?
