Can an ATV be made to work with older TVs with no widescreen simulation mode? Will the ATV even send a signal and start up with an older TV? If most of what I want to watch is in 4:3 ratio, does it even matter if my tv isn't wide screen simulated and would it just cut off the edges of the menus? Is there a converter box you can buy to send a letter boxed wide screen signal to a 4:3 regular tv? Etc. etc. i.e. exactly how much can you get an ATV to function on an older tv?
