Found a post from DVDSHRINK himself:
DVD Shrink 3.0 Beta 1
DVD Shrink 3.0 Beta 1 is now available, for those who wish to test.
The main changes are:
Version 3.0 Beta 1 - 9 Aug 2003
No more compression levels. Instead we have four new settings:
- No compression - original video.
- Automatic - DVD Shrink will choose the best compression ratio.
- Custom - you can select desired ratio (with a slider)
- Still Pictures - as before.
Better quick analysis.
The sample points for initial quick analysis are carefully chosen, and sparse analysis results are interpolated between samples.
New "Analysis" button.
This performs a deep analysis, which (a) guarantees that the predicted target size is met and (b) significantly improves video quality.
New "Analysis Results" file format
The new format is more flexible, used to save results of the initial quick analysis, also deep analysis results or partial analysis results (if you cancel analysis, partial results are saved). Also better checking in case of conflict of CRC values between two DVDs.
Output files are written to HD in one pass, so no longer necessary to make a second pass to fix navigation ptrs. This reduces total encode time by about 5 mins.
Multi-threaded preload buffer (in both analysis and encode modules). While one batch of data is being processed, the next batch is pre-loaded on a seperate thread. This seems to work especially well during quick analysis, where the waiting time for drive seek operations is significantly reduced.
RCE region protection removal, special thanks to Mr.Bass.
New "New Frame" menu option - creates another instance of DVD Shrink, but in the same process. This is used by re-author module which now supports drag 'n drop, or cut & paste, from any window (re-author from multiple disks).
Video preview window shifted to the right-pane, which is where it belongs.
Fixed various strange behaviours in the DVD and Streams View. Also removed the "Compressed" column, since takes up unnecessary space.
Compression % values inverted, so they now represent the ratio of output size to original (small % = big compression).
File reading code now supports output from DVD Decryptor in "Auto" file-splitting mode, or non-split VOB files.
Fixed bug in re-author where only 32 titles could be played in sequence. The limit now is 99.
Added "perform deep analysis" option in backup dialog, thus analysis and re-encode become one sequential operation.
Added "shutdown when complete" option in backup dialog.
Added "remove macrovision" option in preferences (all versions since 2.x have removed macrovision, now it is an option).
Added "remove P-UOPs" option in preferences.
Added "split VOB files" option in preferences, on by default.
Fixed possible problem which may have caused gaps in audio playback.
Removed option to disable menu subpicture streams, as this stream usually contains the menu buttons.
Added option to completely disable video preview.
Moved all hard coded text strings into resource file, so future translations will be complete.
Removed "view Raw DVD" option.
Added "Unreferenced Material" folder, which appears in the main view if material is found on the dvd which does not seem to belong to any menu or title. Previously the existance of this material would cause errors in target size calculations.
Removed "error margin" option - no longer required.
Added "Combine Shared Titles" menu option, which is on by default. Turn this off to seperately list all multi-angle titles (or titles which share the same video with other titles) in the main view. You will need this, for instance, if you wish to re-author only Angle 2, etc.
Fixed TMAP table generation for re-authored titles with angle greater than 1. Seek in PowerDVD etc should now work, whatever the angle.
Various other tweaks and enhancements.
