WD TV LIVE stops playing, need to restart

Dear MrPink,

Thank you very much your last suggestion which I did it and roll back the version from 2.02.32 to 4.01.86. And I hope the films will not freeze and the remute control
functions even next day while it is on AC power. You will not believe me but I bought myself this gadget (WD TV Live Streaming Media Player) 19 pieces to all my family and friends and everybody is suffering from freezing after 20 minutes and remute control not functioning. Thanks again for your recommendations.
Best regards / Zeki
