Hi, right now i'm in the process of burning a DVD with iDVD. Its encoding the video now, so I left it for a bit. So like 10 minutes later I come back and instead of the blank DVD-R I have in my iMac saying it's DVDR on the desktop, it says its a CDR. It's still titled 'Untitled DVD', but instead the CDR icon is showing up. Anyone know why?
