It's likely that its just a misprint on the UK BD.
The BBC US version is in 1080p but without any extras whatsoever, it's on four Blu-ray discs. The BBC UK version seems to be in 1080i but also having an extra disc with the extras from the SD DVD version.
Assuming this information is true, I really dunno if I would choose extras or 1080p. Probably 1080p. I would be happy if I could get any of this information verified
I've also posted on other forums and if I get an answer I'll post it back here
