Hi,

I am also having a problem with dcf files. I've tried using Tunebite (amongst other DRM removal programs) but, again, the software doesn't recognise the .dcf extension. The video I am trying to decrypt is an mp4.

I've found a sample of some C# code that should the file and enable you to extract the content, but i have no clue about executing C# code!!
If anyone want's to have a go (please!), here is the C# code: http://www.example-code.com/csharp/oma-drm-read-dcf.asp

Has anyone found a way to decrypt this type of file?!?

Thanks
