Import DVD has the following issues:
If you have selected all 25 segments (25 vob files), and all of them and
ISO ripping method each one generates a 7gb file, which is the whole DVD.
Thats 175gb
If the user selects ISO there should be no other options.
Using Perfect mode fails to rip the menu on my title, and the files are
placed in the same directory instead of one directory for each DVD.
ISO rips of normal(protected) DVD are useless because the subchannel data
that contains the encryption key is not copied so if you try and play the
DVD its a jerky slideshow with pixelation. The ISO dump has to be
augmented with a seperate file for the subchannel data in a format thats
compatible with some player. Like Virtual CD by H+H software group will
emulate a virtual cd/dvd drive from a file, and several file formats that
supports the ability to make the sub-channel data available to the dvd
playing software.
Mount and playing from linux has the same problem because "mount -t
iso9660 <source> <mount point>" still does not have access to the
subchannel data.
If you want a working ISO rip you need to do the rip, and then extract the
vob files decrypt them and put them back.
I suggest "mount -t iso9660 -o loop /path/to/file/whatever.iso <mount
point>"
cp <mount point>/*.vob <temp location>
decrypt
now you have to re-insert the files into the ISO.
I have never tried it but you might be able to cp them back into mounted
ISO image.
