[GTALUG] Raspberry PI hdmi problem

Evan's post reminded me of a problem I have left on the back-burner for a year. I also have a RPI Model B that I bought as a media centre, but for that to work, it needs to go through my Pioneer receiver to my projector (because I have other sources and I need to switch among them). Unfortunately, that doesn't work, although it works if directly plugged in to the projector. I tried at the time to email someone at Raspberry, but never got a reply. When I saw Evan's post, it reminded me that I'd really like to get it working, and that somebody here might know something. Thanks ../Dave
