I want to add a "copyrighted by..."-text on some mpg-files, without having to remix back and forth with avi-format.
If it has to be done a s a text or image or whatever is of no importance, as long as it is possible to apply directly on mpg-file.
I tried a program adding subtitle, but it re-encoded the whole movies - giving a redish tone and lower quality - so that wasn't acceptabel.

Even only "not checked possibilities" would be good enough for me, to try... because I'm less than 3 weeks from deadline with this task
