I'm attempting to burn a Blu-Ray disc using Express Burn. I'm using Express Burn on my 2011 MacBookPro OS 10.10.5 and an external burner (Pioneer BDR-XD05S). I'm able to load the files and create a menu. When I click Burn Blu-Ray, it encodes then begins burning. It has failed three (3) times now, giving me the message "Burn Failed insert a new disc and try again?"
When I try to continue, I get the same message, so I have to cancel and start all over. Any idea what's wrong?
