@CrazyDoc: Does the device pair with Max2Play? Are you able to find max2play as a BT device on your second device?
@igi: You should not need root rights to find max2play as DLNA in BubbleUPnP or AllConnect. What video are you sending to LMS and where do you display it?
We do not recommend the hardware setup you propose. There are various voltage issues that might occur.
