Hi. I am having a problem with the buffer level in nero. When I burn(Pioneer DVR-108) something, the buffer level jumps from 30% to 70,80%. It wont stay high. I looked around and found this thread: http://forums.afterdawn.com/thread_view.cfm/271824 I went to device manager and went into IDE ATA/ATAPI controllors. I read in that thread that the dvd burner is usually the secondary IDE channel. However, my dvd burner is primary IDE channel. On the list, I have two primary IDE channels and one secondary IDE channel. For my first primary IDE channel properties, my Device0 has DMA if available and is currently in Ultra DMA Mode 5 and my Device1 in in DMA if available and is currently in Not applicable. I assume this is my regular cd-rom. For my second primary IDE channel properties, my Device0 has DMA if available and is currently in Ultra DMA Mode 2 and my Device1 in in DMA if available and is currently in PIO Mode. I assume this is my DVD burner. I was lucky once about a week ago and the unistalling the primary and secondary IDE channel steps worked. I was able to burn normally(with my buffer level high). However, now I cannot burn normally, even if I uninstall it again. I did not try to uninstall from the device manager through DVD/Cd-rom drives. I did not do this because I have two primary IDE channels. I don't know if this is bad or not. I have a media card reader. Maybe that is one of my IDE channels(I have no idea). If you need, I can post my Nero log. If having two primary IDE channels is not a problem, then I will try to uninstall through the dvd/cd-rom tab in device manager. I don't know if this helps, or is right, but my regual cd-rom has cable select selected and my dvd-burner has slave selected. Thanks in advance.
