No, that's true, but I don't need big pixels with hard edges.

Well, how long a video line do you expect a normal vga card to be able 
to drive?

I've seen 30m cables used to drive a lcd pj at 800x600 as well as 
1024x768 with very little visible problems, but I'm not going to run 
that long cables, it's going to be 4m max.

I never said I had a digital PJ, I have a Electrohome ECP3500 CRT:
http://www.crtcinema.com/ehomespecs.html it will happily do much higher 
resolutions than I want to spend the CPU to process.


In any case the point is that I want to deinterlace the video and scale 
it in software and output it via a normal vga card at 100Hz.

I don't want to output an interlaced signal and have it mangled later...
