I just got Directv today and I'm having issues with the format options. Whenever I select the 16:9 I can't use the stretch/crop options. But if I select 4:3 I'm able to cycle through the format options. I have tried selecting /deselecting 480i-1080i without any luck. Is this user error or a problem with the receiver? I currently have an HD H21NC-200 reciever using an HDMI cable to a 50inch plasma.
