Why DVD43 does not recognize an Internal DVD/CR drive in a VM

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.

Sorry to bother you but is www.tempusfugit.ca still a valid address? It just seems to time-out when I try and go there.

I would really like to work out how to use DVD43 in a Virtual Machine, it seems that you may have the answer

Thanks Peter for your interest in tempusfugit.ca

The site is presently being redesigned and will be back up an running very soon.

I will be making posts on the New Tempusfugit (see link on this blog) and also here on this blog "The Technology Muse"

Sorry for the inconvenience but the tempusfugit website had come under attack from somebody that thought that it was being used to "flame" them and their company.

I am trying to get DVD43 to work with a VirtualBox VM. I cannot get the DVD drive to be recognized by the decoder and the smiley face stays yellow
