VBR too high issue

Question

I am using OS 10.3.9 and Compressor 1.2.1
I have a project right now that requires 3 multi-angle video tracks that are 40 mins. each.
I made sure they are all the same identical length. Set in & out points exactly the same for each track in FCP and created my own preset within Compressor to have the same Average and Maximum Data Rates as the 120min High Quality Encode preset. I created my own preset because DVDSP says that GOP needs to be closed and the 120min Preset does not show that to be the case.
Well after spending almost all weekend encoding video (no thanks to a slow dual 1 gig G4) and spending hours designing my DVD menus, DVDSP says that the Bit Rate is too high! That makes me feel like bashing my computer with a baseball bat! I thought I did my research and even created 30 second tests to make sure it would work.
Does anyone have any suggestions to find out why my Bit Rate is too high? And what I can do in the future to make sure I have an acceptable bit rate so I don't waste another weekend?
Also, is there a Compressor update I might not know about that will work with the system I use?
Thank you for any advice.

Answer 1

I was totally wrong about the video.
The User guide is correct.
Audio however is a different matter with multi-angle.
The data rate of all the associated audio tracks add together.
Here is a post from Trai Forrester on an Apple Dvdlist.

Hi Pete and All,
The multiple angle video stream, unlike multiple audio streams in a
single track object, is interleaved. Playback of multi-angle flagged track,
"hop scotches" on the chosen angle, "jumping over" the "not playing" chunks
of video, "bound" within their own angle. The "about 10mbps" ceiling still
applies.
The 7mbps maximum limit for each separately encoded video element that
will make up the encoded multi-angle stream, is more of a function of
distance over time, and the inversely capable limitation of standard
hardware to jump over non playing sections, as the non-playing sections, or
total number of angles in the stream increase (distance to hop scotch).
So the 9 angle stream will still register on the bit rate meter, well
within the specs (7mbps, as the other streams aren't "playing").
Audio streams are different. Even non-playing audio tracks bit rates
must be included in the total.
Example:
9 video angles (each encoded at 7mbps) = 7mbps (only one angle can play at a
time)
8 Dolby stereo audio tracks @224 kbps = 1.792 mbps
Total bit rate for the Track = 8.792 mbps - Plenty of room left to try to
wrestle some subtitle streams out of Subtitler, and include them!
