check on your reciever that openwebif is enabled
if so then as long as your using the correct port (if you havnt changed it then its 80)
and username as root
password left empty
then shouldnt be a problem.
i do know that on the ipad you need to use the older version of vu player and not the hd one as it recogines that your not using a vu+ model
however on the android if you use timote and you select enigma 2, enter your ip of reciever, port 80, streaming 8001, enable login on, ssl off, user- root, password -blank then there should be no problems.
if all fails try downloading and using the vu+ player thats not on the play store but threw the internet browser (on your android)
