audio 2000

I currently have 2 movies with errors in Windows Media Player. Seems that I need the audio 2000 codec. Anyone know where this can be found? It doesn’t seem to be an open source mpeg format, but only a closed source that wants paid... My other 2,100 videos are fine... just these 2 current additions are giving me problems....

Found the solution, thanks to some other posts I had failed to read before asking.... Here is the site to get the codec....
