There's a definite limit to how well one can resolve a signal from background noise. My gut tells me that to get anything useful an alien species would have to be pretty damn close to Earth. That is not to say they wouldn't be able to detect signals that came from Earth, thus proving that we're an "intelligent" species, they just would never be able to make anything coherent out of them much less see a rerun of friends or what have you.
