I have a JVC Everio GZ-MG670 with Everio MediaBrowser software. I have edited a video, and want to burn it. When going through the burning steps, I get to the end and click "write," then get an error message saying there is insufficient workspace capacity and to check the preferences settings. I looked in preferences and didn't see any options to remedy the problem, and couldn't find any info in the manual. Any ideas would be greatly appreciated.
