Just to close out this thread,
I chose to stick with Windows 7 but I did do an upgrade to a 64-bit version. This will allow me to do some gaming using emulationstation. I am running on an older MSI Media Live diva board and I had some concerns about whether I could use 64-bit with the Diva's 5.1 channel D2Audio card that I use to provide 5.1 audio, but it seems to work fine. I was also able to implement EPG123 for both HTPC's, and I think at this point I'm satisfied.
My only regret is that I'm forever locked out of Windows 8.1 which, as far as I am concerned, looks like an ideal HTPC interface. It's really a loss that Microsoft doesn't see that.
Thanks for all the assistance..
