That sounds right. The movie is encrypted and the current volume ID (which is unknown for the moment) and Media Key won't produce a VUK that decrypts the Title Key file correctly.

In order to make this completely work we need to know (1) if the VUK is calculated at all (2) what that VUK is (3) encrypt the decrypted Title Key file with this new VUK (4) change the iso with the new Title Key file bytes (5) burn the new iso.

Keep in mind we are still at step 1 and 2.

But for the moment it appears the Software player notices that decrypting the Title keys (with the "strange" VUK) isn't working. Which is correct since we haven't changed the Title Key file yet.

In order to get any further we need to know if the Volume ID is extracted (which could be a sign that 1 is working) or extract the VUK directly (which sovles 1 and 2). But we can only do that with either a sniff log or a memdump.

It might be possible to do a memdump (or use the key finder) during the 2 seconds you mentioned. Its tricky though... The best way is to let the crash be intercepted.
