DVD95Copy v2.0 "No compression" setting test results

I decided to do another test run on how well DVD95Copy compresses so I used the same DVD like I did in this thread. I wasn't testing for quality, just compression. The DVD is Thomas & Friends-Best of Percy. This is only a 4.35 GB DVD-5 so if I set everything to "No compression" and the main movie titleset to "Fit to DVD", I should get almost a 1 for 1 copy. That's logically thinking. Here's the test results.

Code:
 
DVD95Copy 2.0 settings 

All Audio and Subtitles Kept and DVD Size(MB) at 4464

Total Size         4.35 GB       4.20 GB :eek:   

Different end-size from original input
Here are the Size On disk info for VTS_01_1.VOB and VTS_01_2.VOB combined.
Code:
 

      Original: 1.54 GB   1,656,426,496 bytes 
No Compression: 1.54 GB   1,656,078,336 bytes 
----------------------------------------------          
    Difference:                 348,160 bytes :eek:


My analysis: My main menu VOB, VTS_01_0.VOB has shrunk very significantly! I did this test 3 times and there's still a difference of 129,032 KBs. The transcoded size is worse than the results I had when I did that same VOB with 1.5 Beta 1 @ 100% setting. That resulted in 90,576 KB back then. Anyways, there are still some VOBs present with decreased end sizes.

Yo!

it isn't unreferenced material it's dropping is it?, a bit like the Universal DVD's that have an extra 190mb in the VIDEO_TS.VOB that will be dropped by some programs

I see its in the VTS_01_0.VOB, can you see what video it's dropping by comparing the 2 (maybe splitting them) and if it is referenced in the IFO. I'm sure you can work this one out and I hope you do as I'm interested in your results

cheers

Used DVD Shrink to analyze files off the DVD and there were no unreferenced materials present. So my compression detecting test is still in good standing.
