'Music Box' (Costa-Gavras) - transfer quality?

[Bruce Morrison]

I've just noticed that the Costa-Gavras film, 'Music Box' (with Jessica Lange), is available on Blu-ray in Sweden. However the details indicate that it's a 1080i transfer, although it's not clear whether it's a 50Hz transfer (i.e. with a speeded-up running time).

Can anyone confirm whether it's a 1080i/50Hz transfer (or equivalently confirm the running time of the film on this disc), and comment on the general transfer quality?
