I am trying to burn a blue ray disc on a mac with a external drive. I can burn a blu-ray read-write disc. But when I want to burn it to another blu-ray disc which is a HP to make it a final disc. (It is a HP BD-R) When it tries to burn it freezes encore and sometimes the computer. The point it freezes when the nest box says it is initalizing and moves the bar alittle and then I get the mac spinning wheel when I move it over encore. I have to turn the burner off to recover and unlock Encore.
This is for Windows, but some of it MAY be the same for Mac... except Imgburn is, I think, Windows only, so you need to use something else on a Mac

Create an ISO (Encore) or folder on your hard drive (Encore or Premiere Elements) and then use the FREE http://www.imgburn.com/index.php?act=download to write files or folders or ISO to disc for DVD or BluRay (send the author a PayPal donation if you like his program)
