Philips DVD8421

Hello all,

I’ve recently bought a HP machine which has a Philips DVD8421 Dual Layer DVD Combo drive. I’ve heard that this is a BenQ drive, but which one? And more importantly, how do I region unlock it? I’ve been looking round this excellent forum, but no luck finding what I seek so far.

Many thanks,



On some Malaysian site someone says the Benq DW830a is the same drive (apparently). I’ll have to see how that one gets region unlocked…

Any luck in unlocking the regions on this DVD writer. I hope so,

Thanks for your time
