Sony Vegas Help - Using WM9 audio - older codec

I’m using vegas 6.0 - and the only codecs available are windows media 9.1 - I need to encode in 9.0 - is there a way to install older codecs so that vegas can encode in these older formats? I’ve downloaded and installed a pack from MS that includes the older codecs - is there a way to get vegas to recognize these newly installed (older) codecs?

Thanks
