 Currently in function TuningSignalCheck from file
 mythtv/libs/libmythtv/tv_rec.cpp

 Even if an input is not tuned (such as composite/svideo, etc), an OSD
 message will be presented on each channel change that a timeout had
 expired waiting for a tuning lock.

 Since a tuning lock will never occur on a composite input you will always
 get the message(s).

 The simplest solution is just to remove the OSD message altogether (while
 stilling logging to file/database).
 I have created a patch that does that:
 https://github.com/neoh4x0r/mythtv/commit/41536d7a8437c8aee8becf43a6112d4c55d8c181

 A more complicated solution would be to detect if the input is actually
 tunable and then enable/disable the message as appropriate.
 Note: that might be something as trivial as adding an option when using
 mythtv-setup to setup the various inputs -- you could have a boolean flag
 that indicates if the input is tunable.

 Granted this is not a critical/severe issue, but it is a very annoying
 issue that will always happen on non-tunable inputs.
