I plan on running at least 3 extenders come this fall. I imagine they will be hitting recorded tv more than live so I guess 4Gb is where I need to be. I wonder how much RAM is needed to support the 8 extender limit.
Also if I use the WHS app to move recorded TV off the HTPC is the network smart enough to route the data straight from the server to the XBOX or does the HTPC play it and does the extender watch it through a terminal service view?
