I must admit I have few problems with K3b, other than sometimes it tries to write to old, cheap 4x or 8x DVDs at 16x resulting in some failures, so I always manually set the speed. > > When I insert a DVD-R SL, GNOME (really, whatever GNOME talks to) > > recognizes that a valid disk has been inserted, and takes the > > appropriate action.

Trying different media is probably a good idea, but expensive if you need to experiment. Maybe just buy one or two of each before getting a spindle of 25 or 50 ;-) -- Bob Cox.
