Alright, so I have the Revue box and I have a few mac computers in my house. I have tried both Twonkyserver and MediaLink. Twonkyserver seemed clunky compared to MediaLink. I am hoping to eventually replace my AppleTV with the Revue. Currently I have playlists and files setup through itunes. MediaLink will allow me to view my playlists and information attached to the files instead of just browsing a heirarchy list of the files. I have episode names and descriptions and genres, so I would like to be able to still access this. When I use MediaLink I can view all the files but I don't get any playback of the files. Everything I have encoded was done through Handbrake with a Universal .mp4 or .m4v file. Files play fine on all my apple and android based devices. I'm trying to figure out if this is an issue with the mac servers, my router, or if the Revue just wont sync with mac servers yet. I've seen people talking about getting DLNA capabilities when setting up a server on PC. Has anyone had any luck with setting up DLNA with the Revue on mac's? Anyone had any luck playing .mp4 or .m4v files? Thanks.
