Exporting Avid DNxHD?

[rawfa]

I´ve just downloaded Avid DNxHD (AvidCodecsLESetup.exe) to do some tests on CS5 but when I try to export I cannot see the option Avid DNxHD.
Am I supposed to install anything else?

thanks in advance

Are you picking QuickTime as the container?

Yes.

Then what are you doing?
