I am trying to find out the exact differences between the USA and the UK editions of the THE PRISIONER TV series boxsets, but I am at a loss here. Maybe it's just me, but, despite the reviews I have read, I don't know still if I should go for one or the other. I would be interested in knowing of differences in contents (bonus materials) as well as in the audio/video quality department. Other than the fact that the UK edition comes in a 5-disc set, while the USA edition is a 10-disc set, I have no real, hard facts on them. And does this mean that episodes in the UK edition are more crammed up, that is, higher compression/lower quality? Oh! And does this boxset image really correspond to any of both releases? Because from the images featured on online retailers, none of them look as a fold-out set to me, but a slipcase. Please, I would greatly appreciate any solid info on the matter. Thanks!
