Hello, I'm having problems with my dvd-rom reading dvd-r discs after I have burned files to them. The dvd-rom will read anything else I insert. I suspect it may have something to do with trying to enable DMA through DVD Region Free. When DVD Region Free prompts me to enable DMA, I select "yes" then i am prompted to restart PC, I select "yes" but PC fails to reboot thus meaning DMA remains disabled. Can anyone please help ? Thanks in advance.
