@vidoman: thanks for this information! Not good at all...
Yes it's funny that Intervideo's website states that Vista is a supported OS for WinDVD 8 and the Trimension feature don't work in my Vista Home Premium... The other things seems to work, but I need Trimension. This is the cause why I bought WinDVD 8.
So I need updates and hotfixes! But I can't update the buyed retail version from a shop because there will be an error at the end of the installation process when tying to update to version 8.0.6.109 downloaded from the intervideo website.
Then I found on the Japanese intervideo ftp-Server this WinDVD Version:
8.0B006.164-46420.WinDVD.SD.IODATA.iUpgrde.exe
With this version I can do an update for the retail version without problems! But Trimension still don't work with Vista with this update...
