Stream movies with cover art?

Hope someone can answer my question. I have been using handbreak to convert my video TS files to H264 for the Apple TV which if anyone has done it knows it takes 3 -4 hours per movie. I am looking for a way to keep all my video TS files on my windows home server and stream them to the ATV without converting them. I know the ATV Flash product will do this but is there any way to get cover art and meta data from content being steamed across the network? Thanks for the help.
