DVD95Copy v2.0 "No compression" setting test results

[2COOL]

I decided to do another test run on how well DVD95Copy compresses so I used the same DVD like I did in this thread (http://www.dvd-backup.net/forum/viewtopic.php?t=565&sid=b125ed7c227857e86fd49ae6a41eb633). 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.

Different end-size from original input



Here are the Size On disk info for VTS_01_1.VOB and VTS_01_2.VOB combined.


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! :eek::eek: 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

So my compression detecting test is still in good standing.
