Just bought an open box from Magnolia, got it home, plugged everything in, and was amazed.
I honestly didn't expect to see any difference on the Playstation 2 upconverted and upsampled out of the HDMI cable, but it looked amazing. Crisp image, just phenominal.
Then, every so often, the video would drop out. At first it would only happen within minutes of the receiver turning on, so we thought maybe it was a heat issue, when the unit was cold it had problems, maybe. But then watching video on a modded Xbox or downloaded video on an Xbox 360, it happened a lot. Like, every three to five minutes, two or three seconds of video will just go to snow. E-mailed Pioneer about it 10 minutes ago, the response said they're open Monday through Friday so I don't expect a response until probably Tuesday.
I tried another TV, same thing. Everything is going into the receiver component, by the way, Wii, PS2, Xbox and Xbox 360, and coming out the HDMI to an HDMI to DVI converter, which was plugged into a Mitsubishi rear projection hi-def display and a Sony Wega hi-def CRT.
