As I say, QuickTime includes both, and we have not (as far as I know) had anyone see it as any more than a minor sign, a courtesy notice.

Well, again, they both have some (limited) value.  If the browser normally has a menu (with save in it), then asking the browser not to offer that belongs in the browser's space.  If the media system has a menu (e.g. a pop-up on the video) or the video can be opened in a media player easily, outside the browser, then the tag also belongs in the media file.

Browsers should not be looking for instruction inside the media files, and media players shouldn't be looking in the markup (which might not be there).
