I'm having an issue with a Pioneer VSX-920-K and I wanted to see if anyone else is having a similar issue.
When I try to use my XBOX 360 through the component input via 1080p, using video upconversion to HDMI, I just get a black screen. However, when I input 1080i from the Xbox, it's working fine. My TV is an Epson 8350 (1080p) front projector. When I connect the component cables directly to the Epson in 1080p, it works fine.
I found a similar thread for the VSX-1020-K, which I believe has the same video processors, that explains a similar issue. The thread is titled "Pioneer VSX 1020 no picture with XBox 360" in the Audio theory, Setup and Chat forum. I'd post a link but I'm just a long time lurker and my post count is too low. The thread is over a month old with no real resolution. (I feel like the thread author was ok with the lower resolution.)
I'm hoping that someone can confirm that 1080p component can "up"convert to 1080p HDMI. Even better if someone can confirm it with an xbox 360. Just for reference, this is an older xbox360 unit that was made before adding the HDMI output. I called Pioneer support, and they believe it should work, but I'm not convinced they really understand my issue. They recommend that I "change the aspect" of the source, which I didn't think applied to 1080p.
