I'm afraid I'm not getting anywhere in this whole video viewer scheme of things. I don't believe that any of my video codecs are "bad". All the various movie types I have play just fine in one or more of my video player programs, which are
Windows Media Player
Media Player Classic
VLC Media Player
Adobe Media Player
I also have tried going back to a saved setting file from 6 months ago, but that did not restore things to where they were then - Opus 9 did play a good number of formats in the Viewer pane back then, but only wmv seem to play now.
You mentioned "Each Preferences page can be reset to defaults via the File menu." I could not locate any "Default" buttons anywhere in the plug-in windows. I guess I must be looking in the wrong place(s). What is the exact path to this? Is it not in the Plug-ins?
I wonder if uninstalling and reinstalling Opus 9 might be the best way to go, Can I just run the uninstall, and reinstall? Or, are there various Registry entries around that will still impact this situation and give me problems?
I have no problem editing the Registry if that would help things. I'd just have to know what and where the keys involved are located. Or, does a *.reg file exist from you which will do that job?
I currently have no problems with viewers for text, PDF, jpeg, Powerpoint, wmv, and the like. It just seems to be the video formats such as MOV, AVI, and FLV that are giving me all the problems.
And unfortunately, if I have the Viewer pane "on", and I have the focus on one of these file types, strange things happen - such as the viewer pane going black, the Opus icon in the right hand portion of the task bar disappearing, and Opus 9 closing - and it will not reload when its desktop icon is double clicked - a reboot is necessary.
Sorry to be such a pest -
