My file sizes and bitrates are way low when I encode a 16:9 (640x360). My VDUB is set up to work well with 512x384. Is there anything I should do to hit my target file size and bitrate (~1400) for 16:9? Do I have to play around with the Overflow parameters? (I'm using B-frames, Motion precision =6, VHQ=Medium, custom matrixes.)

If you are getting undersized encodes, then that would mean that you have quants capped to 2, so the overflow settings won't help. I wouldn't recommend using Q1 anyway since all it really does is blow up the filesize. I also wouldn't recommend 640x360 since it is not mod16.

To increase filesize and quality. I would suggest a higher resolution, probably animorphic. Best is no resizing from the DVD, just cropping. The other option is to use a higher quality quant matrix. If you are using H.263, use MPEG, if you are using MPEG, use a custom matrix.

Alas, you already have a 4:3 input movie (4:3) * 128.
Unless you crop the Y axis so that, after a keeping-ratio scaling, you have the movie [you need Video_Filters___Add Null transform (crop)so that 512x384 becomes 512 x 288 and THEN you resize to 640x360.
But, remember: enlarging a movie is rather useless (unless you want to match DVD specifications and, finally, to create a DVD MPG). If your DVD players can play DivX CD-R, playing a 512 x 288 movie or a 640 x 360 movie created from the previois one will have the same effect (garbage in = garbage out).
