Advertisements The flaws that you refer to are indeed intended TiVo features. Features that have been in the product for quite some time. Unlike many of the generic dvrs on the market, TiVo does not require the user to actively manage their hard drive. If the user wishes to do so, they can change the "Keep Until I Delete" setting when setting up a recording. If you have not already noticed, TiVo is a digital video recorder and its sole purpose in life is to record. When you are not actively using the box, the TiVo will record Suggestions for you. So, when you come home, you have a bunch of great movies and tv shows already on your hard drive. Suggestions are on by default; however, you can turn them off. Most likely, this is the reason for the channel changes. (and, the box may record advertising content that is broadcast on obscure channels late at night, but scheduled recordings take precedence). And, a possible solution to your problem may be to set up manual recordings (recording a channel with an arbitrary start and end time). Now, the TiVo can output video to a tv or any other device that accepts video input. But, the TiVo has no idea how a connected device will use the video stream. Outputting video to another device to be recorded is not a common use case, and certainly not a motivating factor for purchasing a TiVo. What external recording device are you connecting your TiVo to? Why not use that device to record your programs directly?
