Please help, having a nightmare with DVD authoring!

I'm having the hardest time ever trying to build & format my dvd in DVD Studio Pro. I used compressor from FCP as a 90 minutes high quality mpeg -2 (6.2 mbps avg rate) with default settings and no filtering. The only thing I did was crop top and bottom, as the sequence content is letterboxed (720x480). The sequence is 89 minutes long.

Compressor delivers me a fine file that averages 6.145 mbps and the image looking good, except for the very 2 last sequences of about 2 minutes long! They have severe pixelation all over the place...

Now, as I tried to export from FCP only the last 5 minutes on a new sequence, it appears fine, but averaging only 5.5 mbps! The footage is perfectly fine, was shot 24pa with the pulldown removed ok! I don't know what is going on...
I tried to mix the 84 minutes of the first file with the 5 minutes of the new sequence, on DVD Studio Pro, but I keep getting an "INTERNAL MIXER ERROR". Is this because of the different bit rates? Anyway, the DVD content altogether ends up with only 4.4 gig...

Why am I getting only an average of 5.5 mbps when I try to compress those last 5 minutes, if the settings were the same 90 minutes high quality mpeg -2 (6.2 mbps avg rate) with default settings and no filtering??? There is no apparent problems with the footage and, when I click "analyze movie", it also appears as having the same settings as the rest of the footage.

Anyone out there to help? I have spent the past 2 weeks stuck with this problem, which is one of the final steps in the process of making my doc feature, which took me more than a year!

Try sending this question to the FCP forum, or the DVD studio pro forum..Wait, there isn't a DVD studio pro forum. Sigh, just try the FCP :)
 
Well, if you are using VBR compression and the last 5 minutes are relatively calm movement-wise, then of course they will take up less space. Normally for projects I render out a regular DV .avi (.mov for you) and then take that and render out my web and DVD files. You might try this.
 
Also, DVD Studio Pro will convert whatever you give it to MPEG-2, so you may just try exporting a straight QuickTime file from FCP and then see what DVDSP does with it.
