Im using Toast 10 Titanium with Taiyo Yuden DVD+R 16x DVD's on Mac OSX 10.5.8 with a LaCie d2 DVD±RW 22x with LightScribe External DVD Burner.
I have not had any problems burning other brand DVD's, and this is the first error messages I have gotten with these DVD's. This is a brand new package of DVD's and the first time using this brand. I tried the first two DVD's in the package, and have gotten error messages.
The first time, I had the burning speed on the default, "Best", and I got the error message, Sense Key= MEDIUM ERROE, sense code- 0x0C WRITE ERROR.
The second time, I switched the burning speed to "16x", and I got the same error message, and when I clicked ok, I got an additional error message that said "Sense Key=Illegal Request Sense Code= 0x21, 0x02 Buffer Underrun.

Taiyo Yuden is listed as one of the compatible brands with Lacie burners, and I know its top quality DVDs, plus its a brand new package...so Im not sure what going wrong? Any help is greatly appreciated!
Thank you.

Is this what your referring to?
