Probs with Pioneer a05

This burner always worked like a charm, and i never had problems, untill… yesterday! I installed winxp on it (with sp1) and now it wont burn dvd’s anymore. Data cd’s are still no problem.
I have the latest firmware plus aspi installed. I also tried different burn programs, and media. Anyone know’s how to fix this?
Im fucking up all my dvd-r’s :frowning:


thnx in advance!
