Has anyone upgraded to this option? I don't really care about viewing JPEGs or listening to my mp3 collection-just viewing recorded shows between the two units. Is it like having one four tuner unit? Will one unit send a record "job" to the other if it's already scheduled for two simutaneous recordings (like ReplayTV units will do)? When watching material recorded on another unit in the home, is the program "streamed" from that unit or is it transfered to the viewing unit's HDD? I'm not worried about setup as i'm A+ and Network+ certified, and I just bought a home and plan to run Cat5e or Cat6 throughout.
