Does anybody know if the DNxHD support for Alphas when rendered in AE has been broken?  It used to not work, then it work for about a week, then I upgraded to 2.8 and it doesn't seem to work again.  I am rendering animations in AE on a MAC, and importing into PC based MCA.  I have done this for years, but recently the DNxHD alpha support has been wonky.  Any suggestions?  I was wondering if QT 7.4.5 is not compatible with the DNxHD codecs. 

TIA
