On the other hand, if you want to record two full QAM streams to a single PC and you don't have a gigabit switch, the HDHR will take 80% of the bandwidth from that PCs. Actually, it will be worse because you probably can't get 100% of the bandwidth in a 100mbps network anyway.
Yup, very true. Even though you don't technically "need" gigabit, if you are running multiple media machines in your house OR have a single media PC with a boatload of tuners AND are recording to a network location, you need gigabit. Live tv streams can hit 40mbps, and that's ONE way, for display only, try writing that same stream to a network location at the SAME time, without stuttering, and you'll realize 100mb just aint gonna cut it.
I run hard wired gigabit throughtout the house, with good gigabit switches (mostly Netgear pro stuff), and can stream 5 HD streams to my HTPCs AND write 2 of them at the same time with no degradation of the network or the machines. As soon as I try to initiate a third stream for writing, the network pretty much comes to a grinding halt and I start getting stutters all over the place. All this writing is to my WHS array btw, no RAID.
