Hack your TiVo! Here's how (ZDNet)
For those who have Linux-based TiVo box, here's a ZDNet article on
hacking them. "
AS WITH ANY good hacking article (and this will only be a fair one), I should warn you up front that proceeding further could render your TiVo useless, void your warranty, violate all sorts of end-user licensing agreements, and, in extreme cases, kill you (if you happen to touch the unshielded power supply inside the box while having an especially unlucky day)."
