Thanks for that info.
I was thinking HDHR networked ethernet tuners were dynamically available but you say they are not?
To be honest, I've never done this myself using my own Ceton InfiniTV4 PCIe internal card. And I don't own an HDHR, so I don't know what their drivers support in terms of "tuner sharing/pooling" and static vs. dynamic tuner allocation.
But I did just check the Ceton site, and it appears that with their new InfiniTV 6 ETH (which is a network-based set of 6 tuners, so I guess it's similar to what HDHR kind of is) they DO offer "dynamic pooling of tuners, available as-needed to multiple PCs".
Tuner Sharing!
Unlike the PCI Express and USB versions of InfiniTV, InfiniTV 6 ETH is an Ethernet-connected tuner that plugs into your home network and not to a specific PC. This makes it a great solution if you want to share tuners with other PCs on your network. You can assign specific tuners to specific PCs – for example, assigning tuners 1 to 4 to one PC and tuners 5-6 to another. We’re also adding dynamic tuner pooling to InfiniTV 6 ETH, which will automatically allocate the 6 tuners between different PCs as needed. Dynamic tuner pooling is currently available in beta firmware through the Ceton Diagnostics Tool.
But be very careful: network-based tuners depend on reliable high-bandwidth in your home LAN, especially when multiple tuners are being used simultaneously for recording or live-viewing of HD content.
And if you add additional bandwidth for extender/PC viewing of HD content, well you're easily now above 10/100 network capability. And it's not just going out and buying a gigabit router that will solve your problem. You truly do need to have Cat5e or Cat6 cabling from the router to other locations around your home (where there might be other PC's with gigabit NIC's, or gigabit switches to support multiple attached ethernet devices around that "node").
In my own opinion, wireless is not good enough or reliable enough for my own HDTV needs. A few years ago I simply bit the bullet and pulled new Cat6 cabling to where I needed it, as well as buying a handful of Netgear GS-105 switches for various locations around the house, to connect to my Netgear WNDR4000 router. I also added a Netgear WN604 (10/100 wired) wireless access point plugged into my kitchen ethernet port, since I was not reaching the kitchen with wireless from the router located in the back bedroom.
