Yes, thanks, that does help.
I was getting confused after downloading the various versions of the manuals on the Panny web site they were all consistent about rapid recording from HDD to DVD would record 16:9 as 4:3 with letterboxing, but I couldn't find any reference to standard-speed copying anwhere in the manuals.
Can you tell me if discs carrying anamorphic recordings automatically toggle 16:9 behaviour on other players after they've been finalised?
