Undersize/Undersizing of main movie at "No Reencode"?

[JFerguson]

Movie was "The Other Boleyn Girl", R1. After blanking some extras, it turned out that I didn't need to compress the main movie, so I set all items in that titleset to "No Reencode".

Rebuilder estimated total size of main movie to be 3832MB. Came in at about 70MB under (3767MB). Not all that much, but I could have moved that bandwidth to the extras, and I'm somewhat surprised that the estimate was off, especially when there was no encoding taking place.

Thoughts?

Here's the .RBD file. Nothing unusual, other than maybe Bitrate Redistribution at 100%:

Was there some unreferenced material in the source? If so, it shoud have been discarded.

No susbtitle streams deleted?

3 audio streams removed, 3 subtitle streams removed... but that shouldn't make a difference?

Also, for reference, DVD Shrink v3.2 precisely sized this after 2-3 minutes of deep analysis.

3 audio streams removed, 3 subtitle streams removed... but that shouldn't make a difference?Sure it will... besides, 70MB on a 4,500MB disc isn't significant enough to try and reallocate. Remember these are "estimates".

DVD Shrink isn't DVD-RB -- so what it does really has no bearing.
