Help needed - wd tvlive freezes and remote does not respond

Hi, newbie here. Upgraded today from 1st gen WD TV to WD TVLive. Set up worked ok out of the box, however have had the picture freeze twice when streaming from You Tube. Pressed Back, hoping to get out of it - nothing. So then tried just about every other button on the remote, including the Home and the Power buttons, again nothing happened. Had to resort to pulling the power cable out of the box to get it going again. Very frustrating. Is there a fix, or have I got a dodgy unit, or what? I haven’t messed about with the firmware or anything.

You may try updating it to its latest firmware, and also reset it by holding its Reset button for 4 seconds.
