1) I can't figure out how to make the thing go full-screen - I thought it was the "I" key and I mapped that to my remote but it doesn't work, I have to use the mouse to select full screen after it loads.
Hey ixian,
You still having this problem? I struggled with it for a while and realized that I was not operating in a supported resolution. You've probably already checked this (or moved on to one of the other solutions), but choosing a proper screen resolution got me the full screen functionality with the MCE remote i button.
