Please educate me more on HTPC and using your computer to upscale the resolution the a TV/Projector's maximum native resolution. Just how much control does the PC have. Are you guys using your computers with built in DVD players and outputting from a video card to your display device, or are some of you using an external DVD player, sending the video to the computer to upscale, and then sending the upscaled video to a display device? The reason I ask is we all know how reliable computer software is (or is not)! The actual hardware is usually rock solid but when watching movies, do software glitches make regular annoyances?
