Comment:

 This behavior is possible with a configuration mistake. It could be that
 you have configured each tuner with its own video source.

 If you have two tuners that receive the same antenna signal then, in
 general, you should have only one video source and both tuners (a.k.a.
 capture cards) should be connected to that video source.

 This is how it works.

 The guide data from an EIT scan is associated with a video source. All
 tuners connected to that video source can be used to record programs in
 that guide. It does not matter which tuner is configured to do the EIT
 scan.

 Along the same lines, you only need to do a mythtv-setup Channel Scan on
 one tuner of a video source. All tuners connected to that video source can
 then be used to record programs from channels of that video source.

 If you have two different video sources with the same channels then the
 guide shown by mythfrontend becomes confused; there is only one line for
 each channel but the programs shown can be from either video source.

 Combining all this it means that if there are two tuners, each tuner with
 its own video source, a Channel Scan is done with each tuner and but then
 a partial EIT scan is done on one tuner and a full EIT scan on the other
 tuner, you can get exactly the behavior that you describe.

 Please do check your configuration and report your findings.

 If the problem persists then please give a more detailed, step-by-step
 description on how to reproduce the problem, preferably on the latest
 master.
