Advanced mixed-angle "illegal angle situation"...stumped!!

Question

First off, I would like to thank in advance anyone who takes the time to read my detailed post and tries to help. I have read the posts on this topic before, but I have not been able to solve my problem.
In detail:
I am doing a project for a client, and part of this project involves a mixed-angle track. We shot several different camera angles of his car (two from within the car, one stable tripod shot as the car passed the camera coming towards you, one stable shot as the car passed driving away from you). There were four different angles shot, and one combined FCP shot showing all four simultaneously for a total of 5)
Step one-the angles:
Angle 1 (V1): From 01:00:00:00 to 01:01:02:22 (A FCP edited shot with all the clips sized down to about 40% of original size so all angles are visible simultaneously.)
Angle 2 (V2): From 01:00:00:00 to 01:01:02:22 (A shot of taken from the sunroof view of the car as it drives. This shot is the only one with the same length as Angle0)
Angle 3 (V3) From 01:00:03:01 to 01:00:51:25 (A shot taken from the passenger side as the car drives with the rear view mirror slightly in shot. As you see, this shot does NOT run the length of V1 or V2)
Angle 4 (V4) From 01:00:11:11 to 01:00:28:28 (A tripod shot taken from a specific spot on the road with "its back" to the car as it comes towards the camera, so the view is of the car as it is driving away)
Angle 5 (V5) From 01:00:27:17 to 01:00:50:22 (Another tripod still video shot taken from a different spot on the road facing the car as it comes towards the camera, so that the view of the car is an approaching view, and the car passes the camera.
Audio is a combined sound of all four events as they occur mixed togther to form one Dolby 2.0 ac3 stream at 192kbs.
All of these shots are synched up as they happened in real time, and in looking at the various FCP timecodes, you can see that the different video angles "weave" in and out of one another.
Some various markers were placed on the footage in synching it up (NOT chapter markers for this purpose..only timing) and those were left in the individual clips.
Step two-once the video was synched, a separate FCP sequence was created for each angle to be encoded for use in DVDSP4. I then placed Chapter markers-precisely accurate to the frame where EACH video event intersected another. (Example: Angle starts at 01:00:03:01 so I put chapter markers at this precise point on angle 1 and 2 as well) Chapter markers were placed on any and all intersections of beginnings or ends of the angles that weaved in and out of other angles. This was done so the GOP's would match for later transcoding.
Step three-transcoding with Compressor.
Exact setttings for first run..
Video-(apple preset) DVD: Best Quality 120 minutes - 4:3. The ONLY change made to the audio or video preset was checking the INCLUDE CHAPTER MARKERS ONLY box in the extras portion of the video encoders for all tracks so the encoding would ignore all markers but my chapter placements.
Audio-Dolby 2.0 preset within the blanket apple preset mentioned above.
Step four-Entry into DVDSP track for trial run.
Exact steps:
Dropped angle 1 into V1
Dropped angles 2-5 into V2-V5 in accordance to the chapter markers governing where these angles should be "sandwiched." No problems here...no error messages. Flawless. Everything going well to this point.
Step 5-Ctrl, Simulate Track...and...here it comes...
"Warning-Illegal angle situation. Only the main video angle will be simulated."
Step 6-Went to Apple Discussion boards. Saw the various posts regarding the maximum bit rate being lower than 7 just to be on the safe side, and VBR turned off to be absolutely safe.
Step 7-Re-transcode all video angles with one pass, non VBR, "include chapter markers only" checked, and max bit rate of 6.5-same audio file as orginal attempt. Dropped video angles again into the respective timing containers in DVDSP. Once again, we get "Warning-illegal angle situation. Only the main video angle will be simulated."
I am stumped. I have tried to describe my process up to this point as precisely as possible and am also on a strict deadline. The mixed-angle feature was a big selling feature for us to this client. I know and hope the answer to this issue is something simple.
Again, thank you in advance! These message boards have always been a great help because of the generosity of those in the Mac family!!

Answer 1

Thank you all for your responses. Here are my several confusions, however.
As long as the GOP's line up, I was under the impression that a MIXED, (not a MULTI) angle project does NOT have to have clips of the same length. Or at least this is what I read in the Ramseier/Sitter Certified training book on DVDSP. This is pulled right from the book:
"About Alternate Angles
DVDSP lets you create two different types of alternate angle tracks:
Multi-angle tracks, in which each angle is exactly the same length as the main video stream.
Mixed-angle tracks, which include alternate video streams that are shorter in duration than the main video stream. Where there's a space in the mixed-angle stream, DVD players revert to the main video stream, which they play until the mixed angle appears again. Mixed angles save disc space for alternate angle streams that do not need to run the length of the entire track. Technically, all angles in the mixed-angle tracks must be sandwiched by markers-one marker at the front, and one marker at the back."
The frustration of this is that I have been successful with Multi-angle tracks. Because I am working with a DVD-5, I cannot afford the space to have ALL these angles run the length of the entire mixed angle clip that I mentioned above. Chapter markers were placed at all intersecting points to the frame, and "include chapter markers only" was checked so that the GOP's would line up precisely with one another.
The only thing I have not tried is compressing at the lowest possible CBR I can while trying to maintain the quality of this footage with minimal motion artifacts. As I said, this is footage of several angles of a car accelerating to the speed of 85mph...so I am also limited to how low I can compress because I will get nothing but blur after awhile. I will try to recompress with the lowest possible CBR as suggested.
This is such a small part in the perspective of the overall whole of this project for my client, but it is extremely important. Again, I appreciate all support and free-time you all have given, and any additional detailed suggestions are desperately welcomed!
Peace
