I have had my LTR-40125S drive for 3 weeks now. It has burned data cd's of all kinds just fine. Today I tried to burn audio and am getting constant buffer underrun recoveries. The drive is not getting data fast enough. I have a multiboot config with WinME/WinXP/Win2000 and get the same prob on all of them. My controller is set for UDMA and like I said I can burn vcds/games/apps/etc fine. The same prob is occuring in cdmate, blindcopy, nero and fireburner. I have tried multiple audio files of different sizes/types/etc. and still get this error.
If anyone else has this problem or solution please let me know.
