I had an older couple of drives in my system and I stumbled across your board. I combed through it to determine which burner/reader combo would allow me the fastest DVD ripping and burning, and I decided upon the combination of an AOpen 1648/AAP Pro and a NEC ND3520A for burning.
However, I am completely stymied as to why I can’t get them ripping any faster than 3x, and that is the NEC (only after I applied the speedhacked firmware). The AOpen won’t rip a DVD9 disc any faster than 1x.
DMA is enabled for both drives. They are Master and Slave on my second ATA controller. In my Device Manager, they are set up as Ultra DMA mode 2.
I am running XP Home on a P4 2.8 GHz processor with 2 Gig of RAM, and using DVD Decrypter 3.5.2. I think the firmware on the AOpen is right now set to 1.0.
Any thoughts? I really appreciate your assistance.
