Is it fair to assume that the test I describe above will always return correctly on a virtual drive (i.e.

I'm guessing it be a bit simpler in your own code. don't have to get the key, as already got the key for this VOB, assumption is that DVDs don't rekey within a VOB, never actually read the spec)ģ) read to actually do a read that decrypts a block, one doesĭvdcss_read(input, tmp_buffer, 1, DVDCSS_READ_DECRYPT) to read the block that has to be decrypted.Ĥ) putting that together, basically what my code did was a) do a regular read() b) do my test c) if test says scrambled, do a dvdcss seek/read to correct location.

Would prefer not to as I only have 4 user changes on my drives. But if I need to change region codes just to watch it then I guess I will. AnyDVD did add the css keys to the key archive.
