I've just purchased a Philips 1640G and when I try to burn a DVD, my PC gets TOTALLY frozen.
First I tried with DVD decrypter: the pc hungs when writing lead-in.
But If I disable DMA, it works. I've installed the via 4in1 drivers, and I'm sure DMA is supported by the driver.
Then I tried to burn a CD using Nero, and it worked fine at 40x speed.
After that, I tried to make a copy of a movie with DVD shrink. The PC hung when the recording was almost finished,
at the writing lead-out stage (but the copy was OK).
The OS recognizes the driver as PBDV1640P, but the model is actually PBDV1640G (is an OEM version).
AMD 64 3000
ASUS A8V Deluxe
Primary IDE Master: HDD
Secondary IDE Master: PBDV1640P
Thanks in advance for your help.
