If it did, change the association of the screens to the MythTV screen, ie.
//to associate LiveTV with Myth:
UPDATE MediaType_DesignObj SET FK_Screen=48, FK_Screen_OSD=128, FK_DesignObj_Popup=4898 WHERE psc_id=3 ";
To change back to the VDR screen:
//to associate LiveTV with VDR:
UPDATE MediaType_DesignObj SET FK_Screen=117, FK_Screen_OSD=278, FK_DesignObj_Popup=5576 WHERE psc_id=3";
The SQL statements above are to be used inside of the pluto_main database as user root, ie.
sudo mysql pluto_main
