My HP came with a burner that is set up with LightScribe. It seems to have so much baggage that it was messing up some software I was using to eliminate the region code (so now I don't need to wait for a film to make it across the pond in Pal1, I can just watch it from the UK or Germany or Oz or wherever). I did a little research and learned that LightScribe was probably the problem. I bought an inexpensive Pioneer DVD burner and made it the master and put the HP DVD burner as the slave and completely removed the CD player. Works great this way.
