Pick an input (such as Video1) and make sure it is set for both DVI-1 and the optical input that you connected the DirecTV receiver to. Once you've done that, try switching to that input while the projector is set to the DVI input (if you're accessing the menu on the projector, it must be on a different input since the 990's menu isn't displayed on the DVI monitor output) - let us know if that does the trick or not.

Ok..did it and nothing. Since I'm HDMI out of the Directv box and DVI into the 990, there's no additional connection needed (i.e. component) from the cable box to the 990 is there.

That's really odd. Do you get audio but not video, or is there just nothing at all?

dah..you know what, I setup the spare Video input but didn't plug anything into it. That explains my frustration. I just hope this doesn't boil down to being a problem with the 990's DVI inputs. Let me give it another try and I'll be back.

Gonk, understand that connecting as mentioned means a component connection and not DVI. My projector outputs are HDMI In, S-Video In, PC In, Component 1 & 2 In & Video In. Am I missing what you're asking?

Ok, I figured out the correct configuration and still no audio or video. The 990 is showing "Digital" flashing in the front panel. Can this mean there's something wrong with the 990. Is there another way to make this connection to get a/v out of the cable box? I gotta get this working before Giants vs Cowboys game on xmas. :-)

anyone can chime in!

If you've got the "Digital" indicator flashing, then you've either not got any digital audio output from your DirecTV box - the 990 is looking to the specified digital input (identified at the right end of the display, next to the input name) and finding no signal to lock on to. If there's also no video even though you have the input's video source set to DVI2, then either the DirecTV box is not outputting anything to the HDMI, there's a problem with the cable, or the projector is not on the correct (HDMI) input. What is the specific model number of the DirecTV box? I'd like to track down a manual for it online and see if there are any possible issues happening there...

ej, if this means anything, my RCA DirecTV tuner can only output either DVI or component video - not both. I have the DTC210 model. There's a tiny selector switch on the back of mine that had me scratching my head until I found it. That wouldn't have been funny during football season...

Model H20...and before I made these changes, HDMI out the HD Directv box worked fine.
