no, if you burn cd's in linux, you (as far as I know) never have to mount the disc when starting
if you do, I think the burner won't do a thing for it....
mm could there be something in your app's setup/config that needs to be changed? mine does some search when I start it (xcdroast) and it takes a while...though it might be because my PC isn't the newest there is
hehe
