This might be a noob question but I’m finally gaining confidence to modify skins in meaningful ways to make life easier for my less-tech-savvy mother.
If there’s something I should do in future to answer this myself would appreciate a pointer. 
– My mum watches a streaming add-on with mobile hotspot with intermittent download speed
– I put an extra button on the OSD to shortcut to the “PlayerProgramSelect” dialog so she can choose lower quality stream if required.
– I want to change the heading string “Select Program” on that dialog to a more helpful hint.
I went to strings.po in en_gb and found msg 31132 “Select Program”. This string is used in the Custom_1101_SettingsList.xml, which is the general settings menu activated from the cog button on OSD. (i.e. the string is the menu item which in turn activates PlayerProgramSelect.)
I figured this string would be also used in the actual PlayerProgramSelect dialog, but changing it only changed the settings menu and not the dialog heading.
I can’t find the string anywhere else. Is there elsewhere I should look?
Or…am I right suspecting the PlayerProgramSelect dialog is deeper in code that’s unavailable in xml? In which case is the heading string not translatable?
(Which if so I guess this is not a Estuary-specific question but that’s where I’m at…)
Thanks in advance.
