i've researched extracting the files. it's a long involved process hacking the tivo (where you can break the box if you don't know what you're doing), transferring the files, finding software to decode the stream, then encoding the result to dvd format and writing to dvd-r.
unless you have tons of time and patience on your hands, it was recommended to just output to vcr. it ends up taking less time and headache.
i myself will watch what i can, wait for the dvd release, and pay the $80-$100 bones for a fully produced version. i just don't have the time like i used to to play around with hacks and strange software.
