C00D109B I got a CD from relatives with an MPEG file on it. I tried too open it in Microsoft's Windows Media Player. But it gave this error Clicking on this this Web Help button brought me to http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&id=C00D109B which did't do a lick of good. According to Microsoft: Yeah, well that is a lie. I have all this and I have done all this. It does not automatically go out and get the latest codex. Has anyone gotten this problem fixed?
Probably your MPeg file is corrupted. You can try running the same with some other player like Winamp or Real player.
Or else install K-lite codec package. It will do every thing for you. Latest version can be downloaded from 9down.com Try iT?!
