You are looking to the HD Fury to let you use the HDMI out of your DVR and thus free up the component out for the secondary display, because the display lacks DVI or HDMI, correct? Here are my big concerns, one comping from my experience with HD cable boxes (not HD satellite boxes) and the other from a video switching quandary.

No, what I was originally thinking was using the component output of the 990 for the LCD. I now know this won't work.

but it appears that if you have it operating in "Single Mode" the "TV2" outputs will always be active and will get the same signal as the HD "TV1" output (with HD stations scaled down to 480i)

I actually have it operating in dual mode. The SD TV upstairs is also run from this same box. So, that wouldn't work either.
