Reinstall 98% OK

I did a fresh reinstall of XP on Angus (my laptop) this weekend. It all went well, thanks to “Windows FD.” If you don’t know what that is, and need to reinstall XP, get a hold of me and I’ll show you the magic.

However, its automated install of Media Player 9 is fucked up. It won’t play use some very standard codecs or recognize some very standard containers. I tried reinstalling it to flush out the codecs, but it didn’t work. Anyone have any experience with fixing codecs that refuse to work even if install exlicitly?
