Maximum I Frame Interval XVID

For support of editing/merging of multiple DVD movie segments, Miniseries, and TV classics removing ending and next segment commercials, ratings, yaking during credits, etc,
Is there a way in DVDFAB XVID encoding to adjust the Maximum I Frame Rate to 2-5 instead of the default 300? This permits very accurate editing in VirtualDub and others without the need to re-encode the entire video to set the Max I Frame Rate, then edit, and re-encode.

Thanks

Sorry, I think this level of control is hard-coded in DVDFab. No way to control it from the profiles as far as I know. Others have requested it too, make it a feature request.
