A method and system for dynamic channel management of a television based on media center set-top box tuner availability. The method includes determining a last channel a television was tuned to prior to being turned off. Then it is determined whether the last channel is a radio frequency remodulated (RF-remodulated) channel. If the last channel is a RF-remodulated channel, then sending a signal to indicate that the television is on line with the RF-remodulated channel. If a tuner is not available for the television, then receiving an indication of a cable channel that was last RF-remodulated to the RF-remodulated channel for the television. Finally, changing the television to the cable channel.
