First of all I would like to thank Steve J. en "maddrummer3301" for their very fast replies.
Especially the hint of Steve to indicate his version of the ldvdeng.dll made me think... His version is 3.9.12.168, my version (located in the same folder) is 3.9.16.269
So, I have a wonderfull working MF4......I copied the ldvdeng.dll of version MF4 (version 3.9.11.159) to the folder of MF5 (other PC).
Then I tried authoring a dvd with several MPEG2 files, other background music, transitions a.s.o....This didn't work with the original ldvdeng.dll but.....it worked with the copied MF4 dll !!!!!!!
I tried several authorings, the more difficult the better and everything worked.
I'm still waiting for a reply of the Ulead support,, maybe they have the real exact original ldvdeng.dll.
But , from now on, I can at least use this MF5 version!!
