Will PowerDVD 16 Ultra in Region 1 play "Region Free" blu-rays?
Hi DaveF,
If it helps make it clear, there's technically no such thing as "region-free" coding in Blu-ray -- Blu-ray divides the world into three regions, A to C, and what we think of as "region-free" means the region coding in that disc is flagged as "yes" for each one of the three regions. So whatever region your player is set to, that disc will play.
DVDs had a different scheme -- 6 regions, 1 to 6, plus a region 0 that was supposed to be like a master key that unlocked all six regions. Some players' firmware had problems with region 0, on occasion.
Anyway, I hope the info might be useful.
