I've been authoring a DVD with several low-quality episodes on it (CBR 2000) downloaded from the web in Scenarist, but I'm having some difficulty getting Scenarist to work with some episodes that are 23.976 FPS. After encoding, I've tried inserting the proper flags with pulldown.exe, but it doesn't accept the resulting files, saying:

"Error : Number of fields (45) in GOP(# 2) or between sequence_header_code should be equal or smaller than 36."

I know that my GOPs are limited to 18 frames, and it's not an interlaced source like I said, so I don't know what problems I could be having with the GOPs or fields. Any suggestions?
