If I set my Tivo to record a maximum of FIVE shows of (say) Modern Marvels, it goes ahead on its own and records from 6 to 12 and sometimes more. Why is this? What can I do to limit the Tivo to recording the selected FIVE maximum? Does it have anything to do with the fact that some programs are available on multiple channels? This is true, but the channels are not duplicates so I would rather not turn off any of my selected channels. Thanks.
