DumpHD - a HD-DVD / Blu-Ray Decrypter

After a long time of hard work here it is, a new version of DumpHD.

I have rewritten the complete disc detection and AACS processing routines, hopefully i haven't introduced too many bugs

. Despite that, i have integrated two new features, a GUI and BluRay support. Because i don't own a BD drive i couldn't test the BD part so feedback about that would be appreciated.

For the BluRay part, there are three important changes from BackupBluRay:

The keys for the BluRay movies are stored in the same file as for the HD-DVD movies, KEYDB.cfg
The key entry format has slightly changed, it is now consistent with the HD-DVD key format. There is now a key type field and the CPS Unit Keys are numbered like the Title Keys. All up today released CPS Unit Keys have the number 1.
The SHA-1 hash of a different file is used as Disc Identifier
This is the most important change, the new Disc Identifier is the SHA-1 hash of the file AACS\Unit_Key_RO.inf. This change was necessary because the Disc Identifier chosen by BackupBluRay is not unique per disc, there were already duplicate IDs for different discs.

Therefor it is required to convert the released CPS Unit Key entrys to the new format to use them with DumpHD.

Example
--------
Old entry:

Code:

1234567890123456789012345678901234567890=This is my movie  |00/00/00|09876543210987654321098765432109

must be converted to

New entry:

Code:

<SHA-1 hash of AACS\Unit_Key_RO.inf>=This is my movie  |U|00/00/00|1-09876543210987654321098765432109

For a complete description of the Key Entry syntax read the included KEYDB.cfg file.

DumpHD also supports Volume Unique Keys for BluRay discs but currently not multiple CPS Unit Keys per disc. To further improve BluRay support, because i don't own a BD drive, i do need some "supplies". Anyone with a BD drive and a BD movie (and its VUK) who wants to help out, feel free to PM me.
