http://support.microsoft.com/mats/windows_media_player_diagnostic dealt with it. Some corrupted reg files from a bad update a week or so back.
Well, I say Media Player is working now but that's just on the computer. It won't stream to the 360 cos it keeps saying media sharing has been turned off, and turning it on won't stick. And, yes, I've done all the making sure it starts automatically, and has the right registry and ownership, and deleted and reset the library, and all that fucking shit that a google search for "media sharing has been turned off because a windows component is missing or changed" brings up.
