Gary has a 3rd Generation Apple TV, but he doesn't have an HDTV with an HDMI connection. Leo says that Gary can get an HDMI to component adapter. Leo advises checking MonoPrice.com.
There's a converter from Gefen, and the KanexPro. It's not cheap, and he will lose some quality. That's why Leo says it might be time to get a new HDTV. A Vizio TV would be affordable and has HDMI.
