I have a very similar problem -- but my error occurs during writing the Lead-In. Also with a Samsung drive (SH-203B). Same error on both cheap Ridata media and HP media. The HP media has been known to work for 100s of discs so far on this OS/drive. I installed Ubuntu Linux as a dual boot and immediately afterwards the drive fails to burn in Windows (must be unrelated, but felt I should mention in case anyone knows otherwise). I tried updating firmware from SB00 to SB04 for the drive. Same error.
