Dvd writing Freezes pc Help Please

Hi can anyone help me please i have just got a pioneer 107 ( Firmware 1.16) and when ever i try to durn Dvd’s on the fly it locks the pc up and i have to reset the pc.
The only way i am able to burn dvd’s is via Dvd decrypter to the Hdd , but with that sometimes the pc locks when reading or when writing :a
Any help would be much appreciated thanks i am using windows xp

You try to copy DVD movies on the fly? (i never heard that before).
You need programs like CloneDVD or DVDShrink to backup your DVDs.
Try to be more specific on your problem so i can help you.
