I am using scenarist to author dvd's. I am starting to put my vcd movies on dvd, but I have a problem. The video stream gets an error in scenarist. It always says the last GOP has 20 pictures and it should be under 18. I am sure the vcd's were done with 5 pictures per GOP, so I don't know why I am getting this error. If anyone has used mpeg1 in scenarist let me know if you have seen the same thing.
