I was an early adopter of the Mitsubishi adapter for my Samsung DLP. The early method where I flashed the EDID of the TV. It used to work perfectly. Still works with my satellite box, actually. However, I haven't used it with my PS3 for awhile, and can't get it to work with my 320GB PS3 (and it worked fine with my old 60GB fat going through a Pioneer VSX 918). The new PS3 goes through a 3D ready Pioneer VSX 521. No matter what I do, when I run the display options setup on the PS3, it won't recognize that I am connected to a 3D display. I have the tv on the correct HDMI 3 input, and the tv allows me to select 3D mode. The Mits adapter powers on automatically with signal. I have tried running HDMI from the PS3 through the AVR to the Mits to the TV, and directly from the PS3 to the Mits to the TV.
I'm really stumped here. It used to work perfectly on the old PS3. I only used it for games, but it worked fine through the old non-3D Pio 918. Today I wanted to watch Prometheus, and it should work fine through the Pio 521.
I'm open to ideas!
