I am running a mac with Nullriver Medialink to my google tv. Setup is easy, only costs $20 or you can use little snitch to block it for free. It has no problems with audio, and video files show up but do not play at this time. The device says that video formats are still in beta and do not work. Not sure if this is an issue with Medialink or all DLNA media servers. Those of you that have used Twonky, do your video files play? I have a lot of information saved with each video file through itunes, hence why I went with Medialink. Twonky simply shows me the files as files. They aren't categorized or anything. Those of you that got Twonky working, do you like it?
