I still need to review the code, but this looks awesome!

I noticed I'm not always getting video info - the line isn't visible. This either needs to show below the OSD, or hide when the OSD is visible, as it covers the preview images.

You might as well change the 'o' key handler to use this:

                 elif action.getButtonCode() == 61519:
-                    # xbmc.executebuiltin('Action(PlayerProcessInfo)')
-                    xbmc.executebuiltin('Action(CodecInfo)')
+                    if self.getProperty('show.PPI'):
+                        self.hidePPIDialog()
+                    else:
+                        self.showPPIDialog()

OK, this is reviewable now.

The session data seems to only be available for the user that owns the server, so the PMS stream detail part doesn't work on a friends' server nor when the current user is a managed user.

This now works with non-owned servers as well, by taking partial data from the transcodeSession if available.

Done.
