I had a dream last night that I was able to get the Tivo software for my box, but not legitimately.
I'll try to recollect what I can from the dream.
In my dream I downloaded a leaked copy. It was a .bin file off of rapidshare or a torrent. I was able to load it on the DCT-6412 by setting up a TFTP server with a certain directory structure and ip address. I plugged this into the Ethernet port on the DCT, and initiated a firmware download by powering it on while holding a combination of keys on the front panel.
Anyway I was using it and it was really cool. Too bad it was all a dream! I remember that when I would push menu or guide, there was a good 2-3 second pause, but once you were in the menu it was pretty quick. The system played all of the tivo clicks and beep sounds. I kinda remember thinking 'is this it??? this is all I've been waiting for?' I also remember a message onscreen about unable to contact customization server at 10.x.x.x\\gixxxxxxxxx\ ivo . I attributed this to the headend not having the server to support some of Tivo's features.
Wow my imagination was pretty vivid.
