believe the warnings.... i got the Talking Heads dual disc set for Christmas. put it in the Pioneer 578-a and the dvd sides would not friggin play! i guess i need a firmware upgrade so in the meantime i figured i would rip the CD sides to my computer. it ruined my Plextor drive!!!!! now i put any disc in and there's constant popping and skipping! i can understand a new format not playing in certain players but ruining one altogether? anyone have any suggestions?
