Hi guys, does anyone know how to disable the region coding on this drive??
i have trawled the net and this site, but somehow still unable to find the info i need!!!
any advice would be greatly appreciated.
Yours frustratingly, a despairing newbie :doh:

Try this site:

EDIT: Apologies - looking back, this unit is a PC DVD rewriter :o. Therefore there won’t be a region-free hack at the URL above. I’ll transfer to the BenQ/Philips forum…
