Yea did the Lame installer and the right click install inf but the one that WORKED was
the K-Lite Mega Pack. When you install the K-Lite pack it will take out any codecs that aren't working or that clash.
Give the K-Lite a go and let us know how you go.

You can get get FormatFactory it's free and quick to convert anything to anything with drag n' drop or batch conversion. (Just uncheck the ASK Toolbar at end of install.)
