Hi JayJ.  Thank you so much for your help and explaining how to install both programmes.  Thanks to you I have been able to install them on one N7 and when my Son visits will install them on his. Many thanks once again. Jeannie105.   

Having purchased three nexus 7 tablets I am confused why I can get bbciplayer and bbc media player and also catchuptv on one of them but the other two keep saying that this programme is not compatible.  Can anybody suggest how I can ge the other two tablets to play these programmes please.   Many thanks for any assistance that you can give me.
