well, i realized that after about spending an hour trying to find/make an antenna. I guess the only reason the new tv works with an antenna is because it is digital.
considering i have an "extra" CC, i tried this, but instead of resetting the screen resolution, it kind of just bunched it up in the left side of the screen, then told me it couldn't boot with the version of Mac OS on the CC, even though it is 7.1 (i think) just like the mactv.
