My Homeplugs are Belkin 200 mbts, I will be doing the rearangmens and pairing them up as you suggest I assume that each group will be Ethernet cabled to its own port on the ADSL Modem.
As I have only 4 Plugs I will group them associated with the HDR's
then if sucessfull I will need another pair for association with the I/P TV.
Here's Hoping
