How can I play a FLV file in Windows Media Player?
What I want is a FLV codec for WMP 12, on Windows 7 Professional x64, that's it.
I'm really happy how it plays mp4s so I don't want to mess up anything, just a clean codec from a trustworthy source.
P.S. I just switched from VLC to WMP after I noticed the huge difference on CPU usage.
