I have several videos that were encoded with XVID MPEG-4 video codec that I cannot get to play correctly on my Windows 7 laptop. Have no problems playing videos with other codecs.
I have tried downloading the latest version of the codec from XVID and installing it, but that didn't seem to help.
One thing that looks odd to me is that when I go into Media Player and do a Help/About the Xvid codec shows up without a binary file listed. Is this normal?

Would appreciate any advice or assistance.
Thanks
