This is in response to a question about taking TiVo programs with you while traveling. Very detailed instructions on TiVo hacking available at:

There's also info on the TiVo community forum, but that guide is all you need. It's relatively easy for someone familiar with working on a PC, feasible but somewhat more challenging for someone who's never opened up a PC. You do have to open up the TiVo and add a board, but no soldering etc. Doing everything in that guide gets you access to your TiVo through a PC interface (TiVoWeb), as well as making your daily call through ethernet (which you can't otherwise do on Series 1).

To extract video, which is never to be spoken of on the community forum, you can get info at the forum listed below. Process is not too difficult once you done the stuff above. No more opening up the TiVo.

Not needed for video extraction, but if you're opening up the TiVo anyway, might as well add a hard drive. Can get kits from:
