Xbox in HD
I recently purchased Component Cables for Xbox (Original) which arrived today.
Through Xbox Media Center, the rather dated hardware of the Xbox handles output to 720p rather well (including DVD Upscaling). I'm yet to try 720p sources, because it refused to play Quicktime trailers I downloaded :( Just as I suspected, it doesn't handle 720p (rather…choppy). Given its age, thats not at all suprising, just means I'll need a HTPC/Xbox360 ;)
Although I could have bought a more expensive cable that'd include digital output (to my Z-5400's I guess), I decided not to, simply because the TV it'll be hooked up to (for about the next 6 months) only has stereo speakers built into the TV.
Given the price of it ($13.60 if you include postage), I wasn't fussed.
