Hello. Thank you for this fine programm. I´d tried v4.4.2. It did not work with my hardware, LG BH-10 LS BlueRay writer on an Asrock Sandy-Bridge-E, X79 mainboard with Win 7 x64. It was only possible to erase a rewritble disk and to burn an image to disk but there was no way to create a data disk or else. There was no drive to select. With this beta v220.127.116.1141, it works fine. No Problems at all. I´ve burned CDs, DVDs and 1 BlueRay Thanks!
