Is it possible to detect the DVD decryption with Ifoedit?

[mouquai]

Hello,

im in a position to see whether Macrovision is enabled or not. But is it possible to detect CSS with the Vobedit and is it containted in the IFO file respectively?

I know how to detect the decryption with the explorer.

Sector size of a CSS DVD is 2054 byte, normal DVDs have 2048 byte.

CSS DVDs are encrypted with a combination of a title key and a disc key. The title key is stored in the sector header. Every VTS has a separate key. The disc key is stored in the control area of the disc which is not directly accessible.

Very interesting, I too would like to know if it is possible to determine CSS/non-CSS status from just the IFOs? http://dvd.sourceforge.net/ shows no information...

You cannot. IFOs never are encrypted.

So, is it possible to see the sector size with Vobedit?

I don't wanna use other tools.

The sector size is always 2048 on HDD when ripped from a consumer drive. The extra bytes in the sector for css are header bytes that cannot be read into PC memory by normal drives (firmware prohibits it).
If you want to know if the files are still encrypted parse the video stream and look at the "pes scrambling control" bits of the pes header. Unencrypted and decrypted files will have both bits set to 0.
