I have a pro 710 with a Tosh 5109. Since I have the lock in full with a progressive signal I bought a RP-91 because it has aspect control. Here is what I discovered. I used numerous DVD's some had a choice at the beginning menu for standard or widescreen. If you select widescreen the RP-91 aspect control does not work at all. I expected the RP-91 in zoom mode to expand so the black bars disappear and the screen would be filled. If you choose standard on the DVD menu then the aspect control works. If you take the same disc with the Tosh 5109 and a progressive signal and choose standard on the DVD menu the screen fills completely and shows the same picture as the RP-91 did when aspect control worked. The result is the same . But what I really wanted was to be able to manipulate aspect while in widescreen so as not to loose content on each side. Most of the disks which had no choice on the menu as to standard or wide filled the screen anyway with the Tosh 5109 in progressive so no aspect control was needed. I see no advantage to the aspect control feature of the RP-91
I believe that a pro720 would have aspect control where hte RP-91 did not and that natural wide or cinema wide would have filled the screen and elimnated the black bars top and bottem even if the disk was anamorphic.
