Does anyone know if it's possible to network the HR20's and send a recorded show from one HR20 to another HR20 across the network? I believe this is something Tivo's have been able to do for a while. I've been reading about media sharing, but that's more for picture/music/video from PC to HR20. I'd love to be able to watch a show recorded downstairs on my upstairs TV between the two HR20's. Thanks!!
