I'm running gutsy and having the same problem. I am trying to burn an ISO created by MythArchivethat is about 6GB, using k3b (which is using growisofs). I have tried it twice, once an the Auto speed and again at 2.5x speed. Both times it failed at 50% through. I double-checked that my hardware supports Dual Layer burning and that I am using DVD+R DL media (memorex).
