I knew the name "batpig" was familiar when it came to Denon receivers. I've seen your site before. It is now bookmarked, as it was on my old computer, and will be referenced often. It is a great service!
The post about the component adapter intrigues me greatly. I will look into it, but my TV is plugged into the optical audio input so I fear the suggestion might not work. For now, I plugged in the PS2 into the front AUX input. This might be a moot point if my buddy gets a new game console and sells us his first-edition PS3 which plays PS2 games (which apparently subsequent PS3 consoles do not - pardon my ignorance, I never play video games and quite frankly don't really care about them, but my gf and her friends play all the time.)
Thanks for the helpful and educational replies.
