Before I get skewered, let me say I still think that the Apple TV is the greatest thing since sliced bread. I can now download rentals from the internet and stream my iTunes movies/TV shows, watch video Podcasts, etc. I love it! That said, I couldn't really see the HD-ness of the Apple TV. I can notice the difference between normal and upscaled DVD's and I notice the difference between normal and live HD TV, but I can't really notice that much of a difference between SD and HD rentals, so I've officially started renting only SD by policy. In fact, I've yanked the HD cord from my Apple TV and switched to component video to preserve the HDMI port (though I seem to be able to still choose 720p over the component video cables, which I thought was impossible). So I'm officially in SD land now, but I can't say I regret it. Anyone else started renting SD movies exclusively?
