Here's something you knowledgable lot can probably help me with, I decided to create 1024x436 XviD's from my set for my 1024x768 LCD projector so as you say the scaling/sharpening has already been pre-done to get the best image, but what are the specified HD resolutions? I've tried google searches but can't find any 'concrete' answers other than 720p and 1080i which I know refers to number of lines and progressive or interlaced.
