On the first point , because of the current high cost of dual layer media most people rip & compress the movies to fit a 4.3gb DVD. Who really needs extras , subtitles, numerous foreign languages etc on a backup.
There tend to be 2 options for this.
- Use DVD Decrypter (www.afterdawn.com) to rip to HD & then use DVD Shrink (same source) to compress to fit single layer DVD.
- Use Anydvd to remove copy protection and CloneDVD2 to rip/compress movie.
With DVD Decrypter not being developed further then AnyDVD is probably a pre-requisite anyway, although some recommend the free DVD43.
There's very little to choose between CloneDVD2 & DVD Shrink except that Shrink is free.
If you really want 1:1 then AnyDVD & Shrink/CloneDVD2 is still a good way to go as not all movies can fit on dual layer anyway without something being removed.
