Darren,

After reading your problem this afternoon , I also joined. I have the same problem. I am on assignment in Russia and got locked into region 5. Same exact drive UJ-820S. Toshiba Satellite A75S2112. I have tried all softwears in the market, Any DVD, 45, CSS and others and nothing works. I tried CSS region free trial and worked, after purchase and installtion it stoped working (DVD was not scrambled). I did not get any refund. I have not been able to find any firmware either. And new unit cost $300.00. Problem is you can not install aftermarket stuff, Toshiba made sure of that.

Any one out there have a solution please let us know.

Thanks,

Fred
