I get this error "Insert a Writable DVD" every time I atempt to burn a DVD and it doesn't mater what type, speed, or size of DVD I put in, none of them work. And my burner works in any other aplication.
@WubNub Presumably you are using DVDA? Which version? There's an option somewhere to use Legacy Drivers for burning. Try that to see if it makes any difference.
With DVDA7 it's Options/Preferences and at the bottom of the Burning Tab.
