Video Bitrate Problem

Question

I looked through previous threads on the subject, but couldn't find anything that solved my problem.
I'm trying to build a dual layer DVD in DVD Studio Pro 3.0.2. All the smaller video files (ie: special features) mux without any problem, but when it gets to the mother file (a ninety minute video), I always get the "Video Bitrate Too High" complaint. I tried adjusting my bitrate settings as per a suggestion on these boards, but it hasn't helped.
Here's the kicker: as a test, I imported that same file to a new DVD Studio Pro project, and hit built. It worked like a charm. Why would the file work in one project, but not another? What's the difference? I've checked the settings, and as far as I can tell, they're identical.
The video is uncompressed (the theory being that DSP would do the compression itself). When we tried putting the file into Compressor, it would tell us something about not being able to locate the source. Searching through Compressor forums, my more-technically-minded associate tells me he can't find a solution for that.
Any and all help would be much, much, much appreciated!

Hi Latauro:
I think the issue could be related with audio bitrate, no matter that DVDSP alert "video bitrate too high".
I don't know what files are you importing to DVDSP, but as you said that are letting DVDSP to make the encode, I guess you are importing not compressed video and audio. If you don't compress audio, DVDSP will encode it as AIFF and will take too much of the complete available bitrate.
If that is the situation, you must first try encoding your audio to Dolby 2.0 (AC3 files) in Compressor and replacing the uncompressed one in your tracks with the AC3 new files.
If you get a low level audio compared with your uncompressed audio files, change the following settings in the standard Dolby preset:
Compression Preset: None
Dialog Normalization: -31 dbFS
About the Compressor error you get, please post a more detailed information about the error message and your system configuration. I'm sure someone here will give you a solution.
