I'm trying to burn an HD DVD movie that I ripped to my harddrive back to an HD DVD disc. I've tried setting the UDF to 2.5 and 2.6 but it doesn't work. The end result will play back on the PC, but I wanted the back up to work on my settop player but all I get is a 'no disc' message from my player or 'corrupt disc' when I play it thru the 360 with external drive. Has anyone else tried to do this and get it to work? I know I could try making an ISO but as I have most of my discs backed up as folders it would be a lot easier and take less time to be able to write the folders back to disc
