Resulted .ISO is larger than Source VIDEO_TS folder?

[MikeGTS]

Hello,

 

I've created a Double Layer image from a VIDEO_TS folder. But it resulted in the .ISO being larger: .ISO = 6.8 GB and the Source VIDEO_TS = 5.1 GB. BUT, if I mount the .ISO with Daemon tools the VIDEO_TS folder inside the image has the right size as the original VIDEO_TS folder. I was just wondering why is the .ISO so larger than the Source VIDEO_TS but mounted it shows the right size ? I did something wrong ? Any help is appreciated... Thank you.

 

 

Also, here the log:

That's due to padding, which is dummy data added to the image/disc so that the layerbreak can be aligned at the start of a cell. This is done to comply with the DVD-Video standard (i.e. the standard that all DVD players understand)
