Abbe,

new things have arisen because the native resolution of video projectors has increased.

clients have started to want to use the full native resolution of projectors....
most professional projectors can at least work at 1280x1024.

so people have started to ask how can i use the full resolution of the projector - and will it give me something more for my trouble? ( it is quite a lot of trouble ... )

So converting 1600x1200 back down to pal or ntsc is what people are used to - and its not entirely sensible as you say.

But maybe soon we might be able to playback native hidef movies - directly at 720p or 1080p into projectors. ( we can already... )
