I belive i seem to have missinterpreted you earlier aswell Myscamore, i did not realise the actual "film" parts, outside of the credits were in wrong AR, in that case, at least for the film it self, fixed is better (IMO) and if you do go the rout of fixing the AR, might aswell fix the credits too, makes the presentation more streamlined.

Sorry if this ends up making things confused for you Myscamore, i should have read more carefully earlier.

And "Italian TV-broadcast version" seems to be the best description so far, good call ;)
