You have the BBC media player app and the BBC iplayer app installed but when you click the iplayer app it launches your browser and you get a page that says that your device is not supported.
And/ Or when you try to use the default Android browser or Chrome (which also comes on the device pre- installed) to view the BBC iplayer it appears to work up until when you try and play a video.
What is causing the problem?
There are three identified and conflating problems.
1. The BBC iplayer app currently does not work properly for Android devices with a screen size of over 7.2 inches. The BBC work around of this "temporary" problem is to have the iplayer app launch the iplayer web site via the tablets browser rather than the app itself. http://iplayerhelp.external.bbc.co.uk/help/tablets/android_app_browser
When you first click the iplayer app it will give you a choice of browsers, the default android Browser, Chrome (unless you have removed the pre- installed Chrome) and any other browsers you may have subsequently installed. Here we are dealing only with the pre- installed browsers that the Sumvision 10.1" Cyclone Voyager BT tablet is shipped with ie Browser and Chrome.
2. Chrome does not work with BBC iplayer. No fix for this here.
3. The default Android Browser will work with BBC iplayer but not with the browsers default settings.
How to fix it.
Firstly don't use Chrome. If you chose Chrome to "always" launch when you click on the iplayer app you need to clear that. Do this by going to system settings/ Device/ Apps/ All/ Chrome/ Launch by default and click "clear defaults".
Secondly you need to change a setting on the default Android browser.
Launch the Android default browser "Browser".
In the address bar type "about:config" without the quotes and hit GO.
Absolutely nothing will appear to happen. However when you then click the three dots in top right corner, then settings, then Advanced you will find that new settings have appeared.
The setting we need to change is "UAString" we need to change it from the factory setting "ipad" to the more appropriate "Android".
All you need to do now is click the BBC iplayer app and when offered the choice of browser select the default browser and click "always". Fixed.
