1) May be you configured Powerstrip to activate a specific sync signal that pleases the Nec. Could be the same thing for me with my Sony 1031. Powerstrip is mandatory to enable composite sync and to make the projector display somehting. Until PStrip starts, no image
4) not everything is dd 5.1 encoded ... I also see my Denon amplifier switch from dd to dpl depending on the sequence
5) Do you really need to change resolutions ? Why don't you set the computer to the resolution you want to use and .. no more. Anywya, Powerstrip can be configured to run at startup and apply the settings you pre-selected automatically.
Do you really need YXY ? If ound that PowerDVD, as long as the desktop resolution ratio matches the screen one, it does everything I need regarding aspect ratio control by itself. Quite easier.
About Girder and keyboard issues, I may suggest the "webboard" IR keyboard .. available in black, small, nice. And, yes, Girder is able of doing such macros. I use it myself with the webboard and a Realmagic remote. For details on my "IR" usage, see http://www.avsforum.com/ubb/Forum12/HTML/004717.html
For Girder, see another thread I started "girder ; the app of choice for your ir needs" http://www.avsforum.com/ubb/Archives...12-004873.html
