Here is a quick video I shot to show how you can make it so your Windows PC can be controlled by a remote control. The idea here is to get it working with the cheap ebay remote, then program the codes for that into your universal remote so everything can be controlled simply with one remote.
This comes in handy when you are using a program like Mediabrowser, XBMC or Plex, etc. Instead of browsing your movie collection using a mouse and keyboard you can just use your regular remote.
Here’s a link to a decent Media Center remote on Amazon in case you are interested in buying one.
