Wal*Mart blocking Mac users as well as Firefox

I saw this on Slashdot and knew that I had to post it here, because of the inordinately large number of Mac users on Mod-Blog. It seems that Wal*Mart has decided that they are going to use a particular type of DRM that is only usable on IE for Windows on their video download site. Now, I am not a fan of Wal*Mart because of many of their business practices and because their isles are too small and crowded (claustrophobia and such). But even if I did use their services this would turn me off completely. If I did download movies I'd be more likely to do it via iTunes anyway, but I think that this is just a bad idea by the Wal*Mart web division simply because of the number of people out there who don't use IE and the number who can't use IE because they run a different OS.
