I had the same problems with the Avid DNxHD Codec Configuration window on Sony Vegas Video. Radio buttons would not work, and the drop down list of frame rates and bit rates was not available on version 12 of vegas. I realized it was because I had the old AVID DNxHD codec installed, and that they would refuse to update when trying to install the new avid dnxhd codecs.

Note the title of my old version of the configuration window: “Avid DNxHD Codec Configuration window – v2.2.1” *should be v2.3.7

Solution: Overwrite the old codecs manually.

After “installing” the new Avid codecs, I think they ended up in this directory C:Program Files (x86)QuickTimeQTComponents
But they should go into this directory and replace the old 2010 codecs C:Program Files (x86)QuickTimeQTSystem

The new codecs should have a date of October ‎17, ‎2011

By the way, the files are called something like this: AvidAV1xCodec …. and there are 8 files. Once I moved them over manually, and restarted Sony Vegas, it all worked!
