Just decided to buy my first DVD writer and picked up a Pioneer 108 for not too much money. However I'm having a few problems trying to get the read speed above 1.7x as displayed on DVD Decrypter. I've updated the firmware to the latest 1.06 version and I've been reading from a few sources that DMA should be selected to improve drive speeds. When I select DMA for my pioneer 108 though the drive is no longer visible in windows explorer. I tried setting it for my old Teac CD writer and it was ok. Lastly I set DMA for my Hard drive and that too was ok. Can anyone help as to why my 108 is no longer visible after selecting DMA and/ or do you have any suggestions as to how the DVD read speed can be improved. Also should I have selected DMA for my hard drive as i'm not really sure what it is doing by selecting it. Thanks in advance for any help coming.
