I use the Moxi products primarily to stream video via Twonky (blu-ray rips because dvd rips won't play for some reason that support could not figure out) but I was playing with the Xbox last night and trying it out.
The xbox can't see any of my video files. I can go into each folder (they are each in their own folder in which I have the video file and the cover art saved as a jpeg) but no files show in the folders or anywhere else when navigating through on the xbox.
I also use PlayOn to stream the dvd rips and the xbox works great with that, however the blu-ray rips tend to stutter and re-buffer on PlayOn which is why I use Twonky for those.
Does anyone know why the videos would not appear in Twonky? I'm stumped. I know it's not an mkv issue as they will play through playon, unless Twonky somehow handles them differently than Playon?
