Using the xbox as a media streamer

So, using Tversity, I was able to get my torrented TV playing on my HDTV last night. I'm super happy about this. Unfortunately there are a few quibbles I've got with it. Streaming media cannot be fast forwarded or reversed, so it helps if it comes in smaller chunks. I used Handbrake to convert one of my Gundam DVD's, and it looks great, but if I want to watch one of the last episodes on the disc, I've got to watch the whole thing. I'm going to change the way I grab media to favor single episodes over whole discs.
