"Open TiVo to backdoor hacks to reveal some configuration settings and features that the "untouched" TiVo does not normally allow access to. Backdoors are the fun remote codes--the ones that require a little more knowledge to get into. You're not going to stumble upon these by accident; you have to know what you're looking for. To use any of the backdoor remote control codes, we first have to ask TiVo to enable the as-yet-inactive backdoors code. The one complication in enabling this mode is that it fully depends on the version of the TiVo OS your TiVo is running. To find out the version of your TiVo OS, go to the Messages & Setup menu and select System Information. You'll see a listing for "Software Version" that looks something like 3.0-01-1-010; that's what you're looking for! In this case, TiVo is running OS Version 3.0--the first two digits are the significant bits you're looking for." If you have a TiVo you really should look into these codes that enable your TiVo to do much more than it does out of the box. Personally, the first thing I do when I set up a TiVo or buy a new one is program the 30 second skip.
