Since no one has one, I doubt anyone has an answer to this yet. But, the writeup indicates that this supports home networking. Since I see a network interface on there, I assume cat5e - and I assume then that means these won't be able to network with the older boxes. But - wondering what functionality it provides. I assume you can watch any recorded show on either box.
I'd love to try this - but $1K to take the plunge. I'd really rather rent these. I know I've spent $900 over the past 3 years renting the 8300, but I've been through 5 of those so I think I'm still ahead of the game.
