I installed windows encoder and tried to convert the avi fiel I had rendered in Vegas to a WMV file but I got an error message saying
" The requested audi codec is not installed on this system. (0xc00d0bc2)@

Any thoughts?

If there's nothing special about the source AVI codecs (try something plain like a AVI-DV25)...

Then I guess you have one sick puppy of a system - corrupted OS?

Maybe before killing the patient to cure it, you should try a reload and/or update of your sound card drivers?

Sorry I'm otherwise out of ideas. Windows Media Encoder comes with codecs... and it only exposes codec choices that you actually have.
