This was some time ago, and I haven't tried to transfer anything else until the other day. The Desktop reported that access to the Tivo's program listing was denied. I ran the diagnostic program and it pointed to the MAK not being enabled.
I can no longer find any reference to the MAK in the Tivo menus, nor in the MyTivo Dashboard.
Has anyone else experienced this problem? Have MAK's been removed for some reason, or perhaps it shouldn't have been there in the first place as I certainly didn't knowingly purchase the Home Networking Kit?
Keen to hear any ideas.
