If it has DRM, you don't own it (part II):
If You Purchased MLB Game Downloads Before 2006, Your Discs/Files Are Now Useless; MLB Has Stolen Your $$$ And Claims "No Refunds"

Background: Beginning in 2003, MLB offered fans the chance to download full games to their computer at $3.95 each. When you attempted to open the media file -- either on your hard drive or after it was burned to a CD -- it connected with a MLB.com webpage to obtain a license. Once the license had been verified, the game would play.

At some point during 2006, MLB deleted that essential webpage. Since then, none of the videos that fans purchased will play.
