+1 for a Roku. I love mine and the Revision3 app is my preferred way to watch Hak5 - the only bit I hate is the US-centric ad before playing each video. I also watch a lot of Netflix and iPlayer on it - definitely £99 well spent.
hfam - Sounds like you need to consolidate TVersity and Subsonic into a plex media server (there is a roku client app) it's a much more elegant solution and that's how I watch my all local media files. It supports all the WAN, LAN, Transcoding features of both the programs you mentioned but in a tidier package.
