Re: So will UK viewers notice more of a difference with the Blurays...
Nope, it sped them up
. The filmed episodes were shot at 24 frames per second, and converted to NTSC 60 fields per second by using one film frame for every two fields and duplicating one field every four fields. The conversion to PAL removes the extra fields, producing a source with 48 fps, and this is sped up by to 50 fps. It's a bit more complicated than this because NTSC is actually 29.97 frames per second.
