Here are discrete / hidden codes I discovered for the TiVo Premiere DVR. These are useful to change resolutions, go directly to My Shows, and put the unit in Standby mode so that recordings will not be interrupted by things like Emergency Broadcast System tests and National Weather Service Alerts. Enjoy!

Clean and tested codes for TiVo Series3 HD PVR. The codes are on panels meant to be linked/aliased to your "pretty" buttons. Four codesets are provided: codeset "0" is a universal codeset and will control a Tivo regardless of the TiVo's IR codest assignment. Codesets 1, 2, and 3 will control a TiVo assigned to the same number. Also included is an Excel sheet with the HEX codes and an explanation of how to modify them for other codesets (0-9). The same info is provided in a TXT document in case you don't have Excel. According to TiVo, these codes will work with prior TiVo Series 1 and 2, provided it is a TiVo box (not Sony, etc.)

A complete set of codes for the new TiVo Series 2 DVR. A few sample panels are included. Note: You'll have to substitute your own TV's codes for the TV-specific functions, such as power, input ,and vol+/-. Uses DVR #1 setting on the remote.
