Are there any preferred blu ray disc blank brands and recording speeds for use with Encore? How about what to stay away from?
I use only Verbatim from these guys:

Taiyo Yudin also has a very good reputation. There are too many bad brands to list.
Use BD-RE during your development cycle.
Changed link to Blu-ray section explaining why to use Verbatim
