I should have mentioned that you'll want to use VirtualDubMod's "Fast recompress" option to make sure it doesn't convert to RGB in between.

For clarification:
<b>YUV</b> is a general category of colorspaces, like RGB.
<b>YUY2</b> and <b>YV12</b> are such colorspaces. DivX uses YV12, which stores half as much chroma information per frame as YUY2.
Now then: YV12 -> YUY2 shouldn't result in any loss at all, and YUY2 -> RGB <i>is</i> necessary, because the popular NLEs all seem to work in RGB internally.

Even if you give it YUV data? I've always heard that if you feed HuffYUV YV12 or YUY2 video (making sure to use VDubMod's Fast recompress, or course), it'll compress in YUY2 mode no matter what settings you choose. But there's still a YUV -> RGB conversion in the process, so I don't see how this would help.
