TweeVo can tweet What Your TiVo Is Recording, it is a simple background tool that polls selected TiVo boxes in your home and tweets what they are recording to a specified Twitter account.
TweeVo is a WPF application written as a "system tray" application, which means it runs in the background without user interaction, but has an icon in the system tray area near the clock.
Unfortunately, WPF doesn’t provide any native support for building tray applications, so we must wedge some WinForms into the mix in order to get a tray icon on the screen. Luckily, this isn’t very difficult.

Requirements:
* TiVo
* Twitter account
* NET Framework
