My Optiarc AD5540A will only read dvd's at .9 speed?

NEC / Optiarc Writer Discuss, My Optiarc AD5540A will only read dvd's at .9 speed? at CD, DVD and Blu-ray Writers forum; This is on my dell 1505. It used to read dvd's at 3.0 speed approx but now .8 or .9 on any dvd. I am using dvd decrypter to rip to the hard disk. Even external usb 2 drives run slower where the external sony used to read at 8

    This is on my dell 1505. It used to read dvd's at 3.0 speed approx but now .8 or .9 on any dvd. I am using dvd decrypter to rip to the hard disk. Even external usb 2 drives run slower where the external sony used to read at 8 or 9 times it is now 3 times. I also tried ripping with the 5540A in save mode and same result .8 or .9. I am puzzled why everyting is so slow. Even in safe mode. I have checked to spyware and viruses and that is not the cause. Does anyone have any other ideas please?

    Check in devicemanager that UDMA mode is enabled.
