Streaming freezing on zgemma h9 hyperion 7.1

Hi guys, I have got hyperion 7.1 image in zgemma h9 combo and there is a problem with streaming channels to android devices. On my phone and tv I got android dream player app to stream tv from zgemma, but from time to time picure is freezing for 20-30 seconds while I watching tv during streaming. I was trying many things in dream player app options to make streaming work smooth, even I started transcoding with poor bitrate 500 kb/s instead of streaming, but it didn`t help. Can you tell me what options do you have on your hyperion system for streaming, or what android app you are using to stream, or what settings do you have on your dream player app? My internet is very good, download and upload as well, so this is not the reason why it`s freezing.
