just to share the info. I've just created a "Full Disk" copy of Harry Potter II -Region 2- which has english and arabic subtitles and english audio only.
the original disk size was: 6.47GB
using DVD2One, size became: 4.36 GB
burned it using ImgTool 1.00.4 -fast tool that uses Nero API to burn, it's also checks for the validation of the VIDEO_TS-
the Image Quality was very VERY good, I give it 98% Image Quality.
how long it took me ?? around 1 hour and 35 minutes.
I have a P4 1.5Ghtz, 512MB RAM, and 80GB HD with HP DVD+RW drive 2.4X
