Might seem an odd question but do most suppliers bother coding region B discs as actually being region B?
I guess what i'm asking is what % of region B discs end up working on US region A machines?
If a high % of region B releases aren't region coded for B, then it makes much more sense buying a region A player. Assuming i want to buy from the US and rent from the UK..
My thinking being that presumably region B are pretty much the last to be released (and most expensive) so why bother region coding them? (I might be thinking to rationally here for the studios though

)
Experiences?
(Note I'm talking mainly about studios known to region code like fox/sony/disney rather than warners)
