Hi tyner. May be difficult to get an answer to your question because most likely few people use zoom and even fewer understand how it works in terms of authoring.
If it's true that studio's turn off that capability for Blu-Rays when they author them, as your manual states, then probably only a developer could tell you whether AnyDVD can re-enable that functionality.
My guess would have been like RBBrittain's in post #2 -- that setting AnyDVD to "Remove prohibited user operations" for Blu-Ray might restore that ability if it's blocked in authoring. T
Thanks testiles for replying. With luck zoom control capability gets restored automatically upon the user executing AnyDVD HD's routine decryption scheme. We won't know unless someone here would run these two very simple tests:
First decrypt the BD as the AnyDVD HD help file explains-BUT be sure to enable any such option as RBBrittain apparently did called "Remove prohibited user operations".
1.) Then with the decrypted BD still in your computer play it with your Windows BD player. Now trying using that player's zoom in (magnify) control. Can you zoom in as many magX sizes as you can when playing a DVD?
Then set player back to normal view. The try changing the playback speed. Of course, don't be surprised as the player will probably (and sensibly) mute the audio. But can you slow the speed down or speed it up in as many steps as you can when playing a DVD?
If your Windows BD player's zoom in (magnify) and slow motion speed controls worked with playing that decrypted BD which make and version Windows player (s)?
2.) Then place the decrypted BD in your (Panasonic, Sony, Oppo, Cambridge, et al) BD standalone hardware player. Now using that player's remote see if you can actuate the player's zoom in (magnify) control. Can you zoom in as many magX sizes as you can when playing a DVD?
Then set player back to normal view. The use the remote to change the playback speed. Of course, don't be surprised as the player will probably (and sensibly) mute the audio. But can you slow the speed down or speed it up in as many steps as you can when playing a DVD?
If zoom BOTH zoom and slow motion controls worked during BD playback which make and model player (s)?
Of course, it would be great if after a BD is decrypted and loaded into a Cambridge, Sony or other hardware player that both zoom and slow motion controls will work via the wireless remote. But if that test done by a member here fails, then I couldn't rightfully expect RedFox developers to come up with a fix for a hardware player.
At least with Windows BD players the good news is that most of them apparently can do speed (slow & fast) control of BDs, their support staff had told me. Indeed, even with encrypted BDs, Cyberlink said their player can do slow motion control over an 8 step range.
As for zoom (magnify) control, if one or more of the member's Windows BD players zoom controls didn't work on a decrypted BD, then I would hope that the RedFox development team would be agreeable to pursue upgrading AnyDVD HD to reclaim what I certainly think is a MOST valuable BD playback feature, as it always was for me when viewing DVDs.
Certainly, both hardware and Windows player makers wouldn't have included zoom control if I wasn't important to many users, as shown here:
