TV Suddenly stops
The reason may be – Some TV tuner devices have an FM radio input as well as an input for a TV signal. Some of these devices cannot receive an FM radio signal and a TV signal simultaneously. For example, if the tuner is in use for FM radio when Windows Media Center is scheduled to start a TV recording, a warning might appear saying that the FM radio session will be stopped when the TV recording starts. If you don’t make a selection, Windows Media Center will automatically stop FM radio and begin recording the TV program as scheduled.
Media centre is not changing channels
If the TV signal is received through a set-top box and Windows Media Center cannot change channels or it changes channels incorrectly, check the following:
1. The infrared remote control cable, also known as an IR blaster, might not be connected. If it is connected, it might be positioned incorrectly on the front of the set-top box. If the IR blaster is not connected or positioned correctly, Windows Media Center cannot send a signal to the set-top box to change a channel.
2. If channels consistently change incorrectly, the IR control codes might not have been configured correctly during TV signal setup. To reconfigure your TV signal, use start – Tasks,- settings, click TV, and then click Set Up TV Signal.
