Advertisements I've seen this covered elsewhere but I haven't been able to figure out how to do this from old threads. I recently discovered that after an old Tivo died that my MAK my new tivo wasn't the same as my old tivo...and no calling tivo didn't help retrieve it. I have a bunch of old shows that I never converted to a decryted file format. I've found an old computer with tivo desktop installed that has the old MAK key...old tivo files play on that computer...vista home premium. Obviously, I would love to pull the mak key so i can decrypt the files on a modern computer, etc. I've heard I can use TDCM to pull the mak key from the registry but after installing TDCM I can't see an option to obtain the MAK. ANy help would be greatly appreciated. Thanks.
