Vegas 8.0a-rendered MPEG-2 too big

I changed my workflow from recording directly to a DVD standalone recorder (using a standalone black box editor) to rendering an MPEG-2 for DVD Architect authoring, directly from the Vegas timeline. My first attempt was on a 1:55 Vegas timeline, which when rendered (according to the VASST training DVD guidlines) to an MPEG-2 to import into DVD Architect was over 5GB, too big for a standard DVD!! DVD Architect had to re-render the MPEG-2 so that it would fit on a standard 4.7GB DVD. I do not know how much loss actually occurred, for this footage was old 8mm film that was converted to mini-DV. So, how do I know how long my program can be for it to be decently rendered only one time (from AVI to MPEG-2)? Do I use CBR or VBR (one or two-pass for the latter)? How high/low should the bitrates be set? Again, I used the guidlines from the VASST training DVD, but they did not mention length of programs, just custom template settings.

Do a search on here (or on Vasst) for calculator). It should tell you what the settings need to be based on the length of your project.

Also, if you got the 5gig file size from DVDA, it is not always accurate and you could have very well just went through with it to see if it would go (ignore the warning).

For anything over (approx.) 70 minutes, you need to use a bitrate calculator to determine your settings.
There's a free on on the Videohelp site or you can download the one I use (note: this links to a zipped file).
Thanks to John Cline for hosting it.
Also, download Vol. 1, Issue 7 of Edward Troxel's free newsletter as it's deals with the many steps in DVD authoring.

edit: j razz is right. DVDA is notorious for incorrectly reporting file sizes.
Next time, check the file size yourself and, if you know your MPEG & AC3 streams are under the 4.3 GB limit, ignore the warning from DVDA and tell it to burn.

I think the problem is in the default settings for rendering to mpeg. I do a lot of interview DVDs and at the default settings pretty much fill a DVD with only 90 minutes worth of video. One would expect 120 minutes.
