I am in a situation where I need to upgrade my projector, and a native 4:3 aspect ratio suits my needs better than 16:9. There seems to be little choice in projectors which are both native 4:3 and take HDMI input. Is it possible to convert HDMI to either component or D-sub 15-pin female?

At present I am using a BenQ PB6200 fed by a component-to-D-sub cable from several DVD players which are switched through a JVC source switcher, so it would be great to be able to convert HDMI to component.

Generally speaking, no. HDMI includes HDCP which is digital copyright protection on it. There are many 4:3 projectors which include at least a DVI connection though and you just want to be sure they include HDCP on that DVI connection... most do.

Since HDMI is digital, you not only would need to strip the HDCP, but would also need to convert from digital to analog.

I always wonder why people bother changing projectors if they aren't going to go ahead and upgrade to an HD projector and 16:9. It's not like 4:3 is going to suddenly come back into style and you can go ahead and upgrade the projector now - and the screen later.

Thanks for the excellent info. I had no idea what HDCP was.

I've decided that I should go 16:9 and make a wider screen, since I do have the room. According to the projector calculator, I should be able to still enjoy a 96" x 72" 4:3 image if I make my screen 128" wide. I do love watching the old movies.

I know this is kind of in the wrong forum, but I'm thinking that I should be OK with the Panny AX200U rather than the AE2000U, since it fits my budget better, and is probably a bit brighter (I have some ambient light in my room). I know it's not true HD, but I seldom watch TV, and mainly watch DVDs upscaled from a Toshiba A3 player (which I bought after they lost the format war, for $65!) or a Philips 5960. I don't intend to jump on the Blu Ray bandwagon for some time to come.
