Well i am on the ps3.. and well i am forced to use composite cables and well when i set it up to use the component it gives me choices to check like 420p,720,1080p,1080i <-- i leave that one unchecked. Because that's what the instructions of the booklet said to do for the ps3 users.
I record call of duty gameplay and I know that is HD. So i don't know what's going on right now. I will try messing with the console settings when I get back home. I am currently at my cousins so I will reply back when I can. =]
