The program gives me a choice between "Actual" speed, and then a bunch of speeds from 4x to 24x. Should I choose "actual" or 24x?
Also, how should I set the extraction/compression priority and error recovery settings? They're both set to "medium" now, but I wasn't sure if that was the default.
"Actual" for some reason seems to mean "The speed you picked last time, whatever that is", so if you've selected a lower speed for a problematic disc earlier, just switch back to highest possible speed, which in this case is 24x.
Regarding the extraction/compression and error recovery settings, just put the cursor over the respective drop-down menu, and a fairly explanatory info box will appear. I'd say that "medium" should be a good setting in most cases.
