I'm working with Nero StartSmart-- which has Nero Burning Rom version 7. I've been very happy with it in the past, but all of the sudden, it has not been allowing me to burn _anything_. It will transcode the video files and the menu screens for burning, but then I'll get a pop-up window-- which I never recall happening before-- telling me to insert an empty disc. I put the disc back into the drive, but the pop-up remains. If I close the pop-up, it aborts the burn. I'm not sure if it's the burner-- a lite-on dvdrw sohw-812s-- or the program, but it doesn't seem to recognize the presence of the blank disc. I use Verbatim, which never gave me any trouble before. I'm pretty well stumped here, and an afternoon of searching hasn't turned anything up with this particular problem. Thanks!
