But ok, I'd like someone's opinion on this. Should I provide an option to discount them? Like, is the active picture area 4:3 or should i just let the whole scanline area be 4:3? You're definitely on the way to convincing me to rip out my little bias feature. :) Poynton in his new book indicates that signals should build to full amplitude over a few samples, and that does seem to correspond to many of the stations that I receive. -- Billy Biggs vektor@xxxxxxxxxxxx
