Can't fit film & extras on project!?!,..not enough space?

Hi all and thanks in advance for any help.
I'm basically new to DSPro and well here's the situation. I have a documentary film and it's 3 extras that I'm trying to burn in the one project. The film is 100min long (21gig) and the 3 extras are A/ the 1st trailer (350mg) B/ the 2nd trailer (120mg) and C/ a bonus footage part (1.6gig).
I've done the layout (with motion video menus) for the MENU, SCENE SELECTION & EXTRAS and it's all together but the project comes in at 4.9gig!..
I know this won't fit on a standard 4.7gig disc (and I can't do dual layer) so how can I get this all burned without losing quality? I'm willing to sacrifice quality for the extras but not the film.
Help please, desperate!
And sorry in advance if this is such a newbie question

Not a problem. The only silly questions are the ones you don't ask. If you're familiar with Compressor you should use that program instead of using DVDSP for encoding. Compressor gives you much more control over the encoding process.
However, you can still use DVDSP for this if you're more familiar with it than Compressor. Use the "2pass VBR Best" setting. Lower the constant bit rate down until all your assets including the audio files total roughly 4.1 REAL Gbytes. Remember that there's a size discrepancy between computer Gbytes and DVD Gbytes. Keep your peak encoding bit rate at 6 or 6.5 to allow the program to assign a higher bit rate to areas of your video that have fast action or abrupt scene changes.
The trouble with using DVDSP is that you can't convert your audio to the industry standard AC3 file format for your DVD. AIF files take up a ton of space as opposed to AC3 files which leave a lot more room on your disc for higher quality video.

Do a Google search for "bitrate calcluator", as there are several out there to lead you in the right direction. If you use VBR in your encoding, the calculations aren't going to be 100% on the ball. But they are better than a stab in the dark.
If you'd like, send me a mail then I can give you a copy of the Excel sheet I use, if that's useful.
All the best,
