Armour Of God (Mediumrare Entertainment) Issue?

[Mythos]

(I know it's a UK disc but it's a HK movie so kinda fits in here, plus I know I'll get better responses in this forum)

I recently bought the Mediumrare Entertainment Armour Of God following a recommendation here.
I have multi-region chipped (bluraychip.dk) Oppo UDP-203 and Oppo BDP-93 but the disc won't play in either player and registers as a Region B disc even though the players will play any other region locked discs.
I have made sure that both were set to Region B.
Does this disc have particularly strong region protection or is something else going on like a faulty disc or something?
Anybody else have the same issue?

Thanks.
