I usually use RipNAS set to "Silent (x4)" ripping mode to keep the noise down and to preserve life in the bearings of the optical drive. Occasionally if I have a lot of discs to rip or I'm retrying after a bad rip I select "Maximum Speed", but I find this very rarely works immediately. It seems to take one or two more discs which are ripped at Silent before the RipNAS suddenly takes notice and switches to high speed. I have tried turning the ripping engine off and back on and this makes no difference. How can I make these buttons in the UI work reliably? Or are they simply broken?
