...To be honest if Movie Album is not going to work with Vista or '7' which I will shortly upgrade to then it is not going to be much use to me...
I just upgraded from Windows XP to Windows 7 and encountered problems after re-installing MovieAlbum...
When run the program I get a warning dialogue: "Failed to update system registry. Please try using REGEDIT." Then "Unknown error occurred during Decoder initialization. (Error Code:0xfffffffb) Exit an application." :-(
I thought about turning to Windows XP Mode in Windows Virtual PC, the new Windows 7 tool available to download for Windows 7 Pro, but according to the diagnostic tool says my processor doesn't support hardware-assisted virtual thingummies.
(http://www.microsoft.com/windows/virtual-pc/download.aspx)
Then I found (by accident) the "Run programs made for previous versions of Windows" in Control Panel\Programs.
Using this I was able to get MovieAlbum 3 up and running, despite Windows 7 insisting it wasn't compatible.
(Another route is to open Explorer, visit C:\Program Files\Panasonic\DVD-MovieAlbumSE, right-click on the DVD-VR application and select "Troubleshoot compatibility" from the menu.)
This removes the warning/error dialogues and allows me to use the program - Hooray!
BUT it does turn the Aero features off until you exit the program. ALSO I can't get the 3DTitle to work anymore. (You select it from the right-click menu, enter the title in the dialogue and then nothing happens!)
I haven't fully tested MovieAlbum in Windows 7, but it certainly allows two titles to be joined, which is mostly what I use it for.
I'd certainly be interested if other people have found better software that can edit DVD-RAMs in this way...
