r/memento

So I bought this DVD with the intention of watching the chronological cut of memento but I can't for the life of me figure out how to access it. The back of the case says it features the chronological cut but no matter what I do I can't find it.

I've searched for tutorials on how to access it but they all seem to be referring to differeny versions of the DVD with a clock puzzle that doesn't exist on this version.

Can someone please give me a step by step tutorial on how to access it as I'm completely lost.

Thanks a lot!
