I'm getting buffer under runs on my phillips 1200 series cdrw. Bought it 3 weeks ago. Seemed to work fine at first. I'm using Office Depot 700meg 80min disks. Will this model recognize those things..or should I go back and buy the 600's? Am I doing something wrong? Software setting problem? Nothing else was resident at the time I was burning. I now have 3 skeets.
