Yippee, 79 visitors. Thanks for coming by...
Just read about a program called ExtractStream, which extracts audio and video streams from a Tivo. It requires TivoNet (a self-installed physical modification to your Tivo which provides an ethernet interface). Looks wonderfully user-unfriendly. I look forward to pissing away many hours messing around with it! (And to think I nearly bought a DVD-recorder to make analog copies of Tivo recordings...)
