I'm using the new WMP (think it's 11) and I burned one CD, and on the second I get an error message that says to be sure that the disk is clean or try a different brand of CD's. I know the CD is clean, brand new, and if it already burned one of the same kind of CD why wouldn't it burn another? My laptop is about 4 years old (HP) and this is actually the first time I've used it for burning anything. Please help!
