In my four attempts, I've used one of each with the Finder method and one of each with the Toast method. Both failed. I am wondering if I might have drive problem, though it burns CDs without a hitch (Memorex - though I just bought a spindle of Verbatim).
Maybe someone else can give me some hints, too...
Got here from your link Clinton!
Sig makes an important point. There is no guarantee that the brand of media favoured by one DVD burner will be equally succesfull in another.
If you have the only one on the planet that likes Memorex, then stick with it!
For the rest of us there are the brands mentioned in your other thread!
