[ubuntu] external dvd writer

view full story

http://ubuntuforums.org – I have an external DVD writer model samsung se-s184m. when I plug into my machine, it is recognized, but when I try to burn a dvd .iso file I immediately get "Error while Burning" An unknown error occured. I can put in a movie dvd and it will recognize the title of the movie but when I try to play it, the movie player just freezes. Any ideas? I am running 9.10 Thanks Tim (Hardware)
