I have a 'Sony KDL32L4000' as my primary television at the moment. Not that good, but it'll do. Anyways, if I purchase a BluRay player, how will the videos look considering that it will only display in 720p. Will the difference between SD be dramatic or barely noticeable. Is a PS3 a good choice for a BluRay player? I think so since it has an upgradeable firmware. Your opinion?
