In brief DvdReMake is the tool to make high quality customized DVD backups. Idea is very simple: the more crap is removed from the disk before compressing it to fit DVD5 the higher quality of the backup DVD you will get.
What can be removed from a typical DVD?..
… A lot! Trailers, extras, studio logos, credits, commercials in recorded DVDs, angles/menus/audio/subpictures in languages you don’t even know, button links to removed portions of the disk, etc …
Here is the guide that describes some of it: http://www.dimadsoft.com/dvdremake/ud_dg_01.php
It is also possible to split a DVD in any way with the program. Actually, you don’t split a disk with DvdReMake - just have what you like on your disk (movie or extra, or even part of this and part of that) with the original menu by simply removing what you don’t want to see on the disk.
Among the “creative” features of the DvdReMake is the ability to
merge two complete DVDs preserving menus.
Best of all no knowledge of DVD internals is required from a user to effectively use DvdReMake. On other side if you do want to get into DVD guts then you will be able to do pretty much anything with your disks using DvdReMake Pro:
[li]Put up to 4 DVDs together preserving original menus;
