The reason that DVD43 does not recognize the fact that a DVD is copy protected in an internal DVD drive when you attach it to a Virtual Machine is because DVD43 uses a Packet Reading technique to read the CSS keys from the DVD.
To get DVD43 to recognize and defeat the encryption is to use an external (USB) DVD drive or not to use XP-Mode and install Virtualbox as described on other posts on this blog.
In addition, an internal DVD/RW drive connected to a VM will be Read-Only - so that the ability to use that drive to write a decrypted DVD back to that drive (compressed or otherwise) will not work.
The packet read/writing of the UDF [Universal Disk Format (Optical Storage Technology Association) - look it up] precludes these operations for an internally shared optical drive.
