MTV vs. Firefox vs. Mac?

So last night I was watching the video music awards and noticed how MTV was SERIOUSLY pushing MTV Overdrive, their "broadband video channel."

Much to my surprise, when I tried to visit the MTV Overdrive section of the site, I received an error that said, "PC users with Netscape, Mozilla or Firefox: you need to run Internet Explorer to use MTV Overdrive."

The biggest problem I have with this is that MTV is supposed to be on the cutting edge of culture, right? And this is something I would expect from a company who has no idea of what's happening online.

Update: Well, it looks like it's not just Firefox that MTV has a problem with. They apparently have a problem with the Mac OS as well. Frances (you may know her from the AR100) sent me an email saying she got the following message:

"Unfortunately, Microsoft's Windows Media Player Plug-in for Macintosh does not support Windows DRM. If DRM support becomes available for Macintosh, MTV will develop a version of MTV Overdrive that works on a Mac."

AdPulp is having the same issue. The possible market share that MTV is alienating grows... it's in the double digits now.
