I just noticed my HD-DVR has a Video On Demand option. Apparently, this recently added and still beta feature pulls the shows over your Ethernet connection and records them for playback when done. Pretty neat!

Between the XBOX 360 (I'm borrowing), the slingbox, the RCA HD-DVD player and the DirecTV DVR, I think I have more things networked in my living room than in my office. :)
