I've been watching EU dvds on the computer, and several different players allow one to adjust the playspeed, so I've reduced it to about 93% for the PAL discs to get them to play at the proper speed. Makes a profound difference from my point of view, and dialogue which blurred by incomprehensibly is now perfect. Portrait of Gina in particular benefits from having the PAL speedup removed. So no worries about any EU discs in my future.
Also, I've been watching the Studio Canal dvd of Falstaff, and the infamous hum which buzzes through Mistress Quickly's speech at the end just isn't there; the sound is perfect. That's good news as it's a widely documented technical gaff of the film. Must just have been a glitch in some distribution prints.
