You're lucky you got it to burn at all. According to xlr8yourmac.com, the 106 isn't supported by Toast. I have a Yikes 400 with 768 MB RAM and 10.3 with a 106. I tried to burn a DVD at 1x using Toast 6, and got a coaster after about 10 seconds of burning, with an underrun error message. When I bought the drive, I bought Dragon Burn, which supports BUP on the 106. I have never gotten a coaster due to underrun using Dragon Burn, and can burn at 4x.
