I am trying to burn a movie with nero. I have already turned the file into a mpeg file with TMPGenc. For some reason when I go to burn after I have selected my settings, the checking disks process stops and a box appeares that say "the medium type in your recorder is incorrect, it is not empty." I have a brand new cd-r in there but they want a cd-rw. I don't see the need for a cd-rw. I think there is something wrong with my cd-writer. I have a hp cd-writer 8200. Does anyone have any suggestions?
