LITE-ON SOSW-852S again..does it read dvd+?

I have also a LITE-ON SOSW-852S in my Acer TravelMate 4001WLMi, and i´ve alredy updated my firmware to PS01, but i still can see dvd-video on my pc.
all dvd´s of my favorite bands and movies, just keep spining an spining until I lose my pacience and eject it… does any one knows what wrong?

You may need to get a true DVD Player software like PowerDVD, WinDVD or VideoLAN.

I have power DVD v5.00, but i cant even read the dvd at all…it dosesnt stops sining…
