Tivo Desktop does not remove its DRM, instead, it adds codecs and stuff so that computer has the ability to decode and play .TiVo files. If you were to completely uninstall Tivo Desktop, you lose the ability to play the same .TiVo files. If you were to take the same files to another computer without Tivo Desktop installed on it, it cannot play on there. Hence, the use of programs such as TivoDecode which removes said DRM and converts to a standardized .MPG which will play on another computer. You can then use any DVD Authoring program to make DVDs in the standard style with .VOB which will play on any standard DVD player, but just writing .MPG files to DVD will only be able to play on those players with .MPG playback functions.
