The majority of the book is working the TiVo at the operating system level to alter the software or to transfer movies. This is advanced stuff that requires a good deal of technical skill. The first chapter of the book does have some hacks that are done from the interface itself, like enabling the advanced season pass. The second chapter covers adding more disk space to your TiVo. Then beyond that you get into the advanced topics; putting your TiVo on your network, changing the software, transferring movies around, and then authoring code for the TiVo.



The book is very focused. The text is well written and the graphics are used effectively. The section on adding disk space is very well done and is better than anything I have read on the web for doing the same type of work.



I recommend this book for people who are familiar with Linux and hardware hacking and are interested in extending their TiVos. For just the average TiVo user you may want to review the table of contents to make sure that you are getting enough out of your purchase.
