I have been using my Ugoos AM9 for some time now with no major problems until now. I have 3 other boxes with TiViMate running no problems but on my Ugoos AM9 just lately and only on my sports channels with my Strong provider the video stutters( TSN,ROGERS SPORTNET) all the other channels work great, all my other 3 boxes are also great no stuttering. I have adjusted the playback buffer size with no results, anyone run into this before?
