So apparently, PowerDVD is not only a standalone player, but also the decoder for Media Center/Media Player/possibly anything else I'll ever have that plays DVDs. So when I uninstalled it, I broked everything.

Thankfully, Dell's customer service isn't total shit when chatting online, so I'll be getting the CD I need to fix it, and possibly other CDs for all my other programs. Hooray!
