Suddenly, my DVD burner (Sony DVD RW DQ-G120A) has problems reading DVD plus media. It can burn and verify pluses, but can’t read them anymore. Others can read plus media that I burn.
I have the very same burner, firmware, OS (W XP SP2) and SW (Nero 188.8.131.52) for the past 2 years and during that time I’ve burnt about 400 Verbatim DVDs (~150 plus) without any problems.
I am suspecting laser but am going to try to first clean the lens and then (if that won’t help) buy the new burner.
