What are the best interleave settings for playback in a divx compatible dvd player (assuming burning the divx onto dvd and not onto cd)

The default in VDub is a preload of 500 ms, and interleave audio every 1 frame.

Is this good for a typical DVD reader in a DVD player? And how does the use of VBR audio affect this? I would think that the more preload the better, but how much preload is too much preload?

I have an avi with VBR audio that has choppy audio during certain portions of the soundtrack. I am sure this is related to the interleaving, since the audio has no problems when played on the computer.
