I've pored over this forum and the XBox 360 thread hoping for answers to this Q, and have not been able to find an answer. In my system, I pass all video singals through a Lumagen HDQ video processor because my projector (Epson 1080p) really sucks at upscaling and deinterlacing.

I believe that all HD-DVD content (at least those currently available) are encoded on the disc at 1080p. Is this correct? (I think the standard actually allows for any resolution, but the industry has not bothered making lower resolution discs). The problem is caused by the XBox only outputting 1080i over component, 1080p over VGA, and not having HDMI support. So the only choice for 1080p output is VGA.

Assuming it is correct that "native" for any HD-DVD disc is 1080p, then that means if I use component, then my 360 will interlace the signal, and then my video processor will then de-interlace it. Correct? Is this really a problem or no?

If a problem, how big?

My adversion to the VGA cable is that I have heard that color reproduction out of the 360 using that cable is not as nice as compared to the component (although that could be corrected with some elbow grease using the processor), and that it would mean another investment in the cable.

Any comments would be appreciated, guys (gals, too).

I'll post an answer to my own question just in case anyone finds this thread via a search. According to the XBox 360 FAQ:

The Xbox 360 supports all worldwide variations (NTSC, PAL) of composite video, all component video resolutions (480i, 480p, 720p, 1080i) and VGA resolutions (from VGA 640x480 at 50 Hz and 60 Hz, passing through 1024x768 at 50 and 60 Hz, to 1920x1080 at both 50 and 60 Hz)

Since the Lumagen currently only accepts inputs up to 30Hz over VGA, one must go with component.

now that all the newer 360's have HDMI can i hook it up to my Lumagen HDQ?

this thread sounds like i have to use component?

thanks!

The Lumagen HDP or HDQ with the latest software can accept 1080i or 1080p24 from the Xbox 360. For all around use playing both games and movies it would be best to use set the output of the Xboy 369 to 1080i. Then the Lumagen will deinterlace the signal to drive your display with a progressive signal.
