Need kickstart with video extraction

[garybx]

I came in during the middle of this era of extracting video from 
Tivo and need some help getting started. I have TivoNet and am 
successfully downloading the schedule via broadband DSL. I 
am also able to telnet into Tivo from my PC. Now I just need 
some explicit instructions about setting up ExtractStream or 
some other extraction tool. Every time I look at a linked website 
or look at a ReadMe file, it assumes that I know WAY more than I 
do, with statements like "transfer the files to your Tivo". What PC 
program do I use? Do I need to execute some program on Tivo 
to allow the transfer? Where do I put the files? Do I need to edit 
some file on Tivo to recognize and use the transferred files?

I hope that someone will have pity on a confused newbie. By the 
way, I'm fairly technically inclined, with programming experience 
in Fortran, assembly, Pascal and C, but I only have passing 
familiarity with Unix.

Thanks,
Gary
