Yes, you must use DVD-R on the 104 and probably on later models as well. I have a Yamaha firewire 16/10/40 and the Pioneer 104 DVD/RW. Strangely I can copy a CD only by placing the original in the Yamaha and copying with the 104. Can't do it the opposite direction. I found you have to be very careful that proper selections are made in Titanium Toast 5.1.2. They don't necessarily remain where you had the settings the last recording.
