Samsung All Share and PS3 Streaming

Hello you lovely people

I have recently found out about and fallen in love with DLNA streaming.

I have also figured out how to stream a movie from my Galaxy Note to my PS3 via Samsung All Share App and watch it on my HD tv which is pretty amazing.

However, there is a little niggle which I was hoping someone could help me with, when watching a movie after 5 minutes the television says the connection between the source (i.e. my note) has diminished. This is because my phone has been in an idle state and therefore doesnt want to perform.

There is a way around this which require me stroking the phone every 4 minutes to make sure it stays awake (how weird does that sound) however I would much rather prefer not to do this.

Does anyone know how to cure this problem.

Thank you in advance
