You could have a separate FM thread but you can't really even go there without getting into "you could instead just go to a junk shop and buy a $20 trinitron." You could have a separate CRT thread but you can't even get very far in that without "isn't there any way to just run this on my Samsung HDTV cause I don't want CRT squeal in my life any more" which just leads you back to the FM. They both solve the 240p problem.
