After further testing, it appears I am only  having problems with a Viewsonic 15" LCD TV (the kitchen's) and the EDID reports 1366x768 at 60Hz. I tried with my 1080p 40" Sony LCD TV and it works fine. Also tried with the bedroom's 32" Toshiba 720p (really 1366x768 too) which also runs fine but EDID reports 1280x720 at 60Hz. Since this FE was intended for the bedroom (it was just more convenient to set up in the kitchen rather than sitting on the bed!), it's not a major issue for now. Once/if I decide to setup Myth in the kitchen, I can experiment with this FE first and just buy another Revo if I get it to work.

Also, after having so many problems with the HDMI sound on my nVidia GT220 on my master BE/FE, it was nice to be able to set up the HDMI sound on the Revo so easily!

Thanks,
Daniel
