I’ve also done a test with DVD Shrink.
I’ve tried to recompress my copy of Saving Private Ryan (DTS , Region 1) to an acceptable 4.7 Gigs or lower.
It told me i could make new menus, but PowerDVD did not show any menus , not that i mind it much ; The importance is the quality.
Pro’s :
Very small program , 340 kilobyte and that’s it. It does everything in one .exe , no freaking .dll’s or installation paths. A big plus for me since i hate tools that fly all over the harddisks , os’es and registry keys.
Quite easy. One goes “clickety-click” and wait for 2 hours and you’re done. It tells what files it has written and shows a nice preview before you select a compression method.
The “Expected file size” results are quite accurate
Freeware. Big plus. Being free usually means : Not supported and shut up about bugs , but i don’t mind that. I paid nothing , i should expect nothing. I can live with that. If the Con’s are not fixed/updated/implemented , i still like the program. Someone put time in this to write it and the least we could do is appreciate this.
Select your own region.
Acceptable image quality.
Con’s :
Menu’s did not work , i don’t know for sure , since i don’t have it written onto a dvd-writer , simply because i have none (yet)
Fixed compression rates. I could only select a 1 thru 8 compression method via radio buttons , there was no method of using a preferred step-free compression rate.
Overall a good product for it’s price 
Did not implement the DTS track , but i haven’t tested it thorough enough.
Image once in a while seems to “hiccup”. Some frames instantly changed scenery , but this was very very rare (about 2 times in the entire movie).
