I am currently living in the US, and would like to buy an LCD TV that will be compatible with PAL/I when I return to South Africa next year. When I am in South Africa I would obviously not use the TV's built-in tuner (which will be NTSC), but will use the tuner in my South African satellite box. Would this work? If so, would only certain TV's apply (I am looking at a Sharp Aquos). If the TV I bought had an ATSC tuner, would that make any difference?
