I am having a similiar problem and have tried numerous things = upddated firmware to PDS7, checked both primary and secondary IDE channels to be sure using DMA, and have tried 2 types of disks (Verbatim and TDK). Still having the same problem. I am able to watch and rip DVD's. I am using and have always used +R disk. Also able to burn and listen to CD's. All was working fine until last week and not sure what would have changed. Any thoughts or suggestion would be greatly appreciated. Log is below.
