On the screen where you choose the resolution and aspect ratio of your HDTV (Menu-6-8), there's a column on the left called "Analog Type". What the heck is that for? The 622 doesn't output HDTV via the modulator, right? (And besides, there's an option to choose air or cable in the modulator setup screen.) And it doesn't receive analog off-air stations, right? So is that option there in case someone has a cable company that uses 8VSB instead of QAM for locals, and if so why isn't it on the locals setup screen, or what am I missing?
