Re: So will UK viewers notice more of a difference with the Blurays...
I don't know if this actually the case for TNG (i.e. whether the PAL DVDs were created as upconversions from the NTSC DVDs, or whether both the PAL and the NTSC versions were encoded from the same source), but Squire assumes that it is, and if so, speculates that for PAL audiences the new HD version will be an even bigger step up in quality than for NTSC audiences.
The PAL DVDs may have not been created directly from the NTSC DVDs, but they were definitely created from an NTSC source; that's the resolution the master tapes were created at, there is no higher resolution film version available (or at least, there wasn't until the HD project was kicked off).
