Your menus look pretty nice, and I'm sure if Laserman were to stumble across this thread he'd have a lump in his throat and a tear in his eye (hell, I almost do), but in the spirit of Laserman's rigorous technical approach to everything, I gotta point out one near-fatal technical flaw I see:
You are way outside the 'title-safe' area of the screen.
This means your menus (well, at least the two from which you've posted caps) will have a whole bunch of the text cut off on most TVs, wide or otherwise. To make sure your buttons (and any dedications) can be read by everyone, everywhere, you're going to have to pull the whole works in on all sides. I don't remember what percentages will do for action- and title-safe areas -- that would probably be Laserman's next post in the thread, if he were around to post it -- but I'd recommend Googling it up and making some changes accordingly. Laserman would be so proud...
