You should know if you have set up a demo tuner.  But maybe you
slipped and clicked on the wrong thing.  If you run mythtv-setup and
go to "2. Capture cards", you should see a tuner listed with "DEMO :"
at the front, followed by the name of the file it is pointed to.  If
you have one or more of them, delete them.

A demo tuner is used to set up backends where there are no real tuners
available.  When you record from it, or play live TV from it, it will
always play the same video file it is pointed to.  I think it will
repeat from the beginning of the file whenever it reaches the end.
Demo tuners are very useful when you want to have a backend in a
virtual machine so that you can try something with it.  They also
allow you to make a slave backend without any real tuners so that
slave backend can provide storage group directories to the MythTV
system.
