It's only my opion but after quite a bit of comparison viewing I've come to the conclusion that DVD95COPY makes the best video copy of a DVD to DVD-R with DVD2ONE being a very close second. DVD Shrink would be third by a fair margin. Just my opion.
When I run the vob's each one made thru Bitrate Viewer,DVD95COPY and DVD2ONE produce similar results-9280/3637.
DVD Shrink-7163/3561.
