It probably is my TV, because I don't use an old SD CRT anymore Wiis and TVs have an inverse relationship. If you have a good TV, your Wii won't look too great. If you have a bad TV, your Wii will look better.
on my 2405FP, i can read OT with composite cables but just barely (very tiny)....when i zoom in of course everything's all good.
i think if this were a couch-browsing situation i'd definitely have to zoom.
but it's also an issue of taking advantage of screen size. there's a black bar aroudn the whole screen for no reason and a HUGE gray bar aon the bottom with the buttons.
