Whenever I try to get my WEI I get this error:
Could not measure video playback performance.
At first I had the MS provided drivers for my ATI X series card so I went to AMD to get new drivers and indeed, I have the ATI drivers now and I get the same error.
Reading around the google results I got a suggestion to turn off Aero and that didn't work either.
That said video from youtube works great! And so do the sample videos in Windows Media Player.
It's a brand new install of Windows 7 and all I did was allow updates and install a couple of browsers.
