I don't have a CRT handy to check but I seem to recall that square
pixels is the correct setting, but perhaps somebody driving a CRT
would know better.
By "Sporting Events" do you mean you are seeing artifacts in fast and/
or unpredictable motion? That's pretty much the nature of the beast
with an encoder in the consumer price range, and a lot of sporting
events are being transported as mpeg streams, even if they are
eventually transmitted as analog by a station or cable system. I see
all sorts of artifacts in live sports, even the SuperBowl looked
terrible to me because of them, and this was confirmed by a few other
folks at the other end of the country seeing the exact same thing.
