dvd drive problem

hi,
recently my pioneer 108 decide not to accept dvd-r to burn.but changed to solely dvd+r. is their anyway i can either change this back or set it to default.your help would be appriciated.

You could try updating the Firmware

Try going to the device manager, find your drive and uninstall it. Reboot and let your pc find it again, if it doesnt search for new hardware wizard and reinstall the generic drivers for it.

thank you for the advice i’ll get right on it.
many thanks
