Thanks for the question! To change the country on your DSTV box, you'll need an MXQ Pro Android TV box like the top result for R749. These boxes allow you to easily change regions in the settings. Once you do, you should see the South Africa DSTV app and be able to access all your local content. Let me know if you have any other questions!
Thanks for providing more details. Since you already have an MXQ Pro Android TV box, let me suggest checking the settings to change the country. The MXQ Pro listings I found allow changing regions in the Settings menu. Look for an option like "Location" or "Country" to select South Africa. This should then make the DSTV app show local content. Let me know if you still can't find the setting. You may need to restart the box after changing locations. Otherwise, some of the pre-loaded models in the search results like "MXQ Pro Android 12 Tv Box Disney+ DSTV Showmax Netflix Preloaded" may already have South Africa pre-selected which could be worth considering as an option. Hope this helps uncover the right setting! Feel free to ask if changing the location doesn't work.
