Having trouble burning dvd's on DVD Architect. I'm using a mac with a partition so I can boot up in windows to edit on Sony Vegas and then make dvd's on DVD Architect. I DVD Architect on the bootcamp C drive which has no more room to store project files. So yesterday I clicked "prepare" and I directed the file to a folder on my external drive. It seems to prepare alright but when I click "burn" I get an error message: "An error occured openina a file on the system. Make sure you have permission to access this file." I've tried to go in and allow permissions both on the pc side and on the mac side but I still get the same error message. Thanks for any help!
