I have a pioneer rptv that has the lock in full. Before doing the rp91 upgrade, when I go to u4 and go over on an anamorphic disc, cycling between auto, zoom, shrink and normal has no effect. On nonanamorphics, it does change. This is due to lock in full or at least I always thought so. Now, I do the upgrade and do this same thing on an anamorphic disc and now cycling through changes the picture size. The tv itself has always locked in full when using the rp91 for both anamorphic and non, and continues to do so. Either this is a fix of a bug, or it's screwed up and no longer giving me the right picture. Anyone have any ideas?
