Any one else having problems with this new ETK? I've uninstalled the old Juicer and installed the new recommended Juicer. Still have bad renders with white squares and rectangles in alpha channel areas.
None of the other DJ products cause this problem.
I had some problems with V6 and some ETK products. In my case it was black frames when I was rendering or previewing in Good ot Best. So might be different issue.
I traced the problem to the version of Quicktime I had installed. In V5 they were working... in V6 they did not. I just used the "update" feature in the Quicktime components to get a later version downloaded and all my problems went away.
