Unfortunately you may be SOL. First I'm assuming from your post that you are using component (some people have reported active DVI) to connect the 8000HD to your projector.
One major drawback (IMHO) of the 8000HD is that it is incapable of outputting 480i if you have selected a higher resolution (by higher I mean 480p, 720p or 1080i) in the settings menus. Since it's an HD box and your are going to want to select 720p and/or 1080i this obviously creates a problem - the box won't output 480i in HD mode. Keep in mind, the 8000HD has an SD mode and an HD mode. The only way to toggle between the two is to literally go up to the box and hit a couple of buttons on the front (can't remember which ones since I never do it but search this thread and you'll find out). If you put the box in SD mode it will output 480i.
For my setup (Samsung DLP), I choose to have SD upconverted to 720p - the set's native resolution - it looks a lot better than having it converted to 480p in the box and then having the Samsung rescale it to 720p.
So not sure I have a solution for you. You, like the rest of us, are the victim of a poorly designed 8000HD.
