Thanks but the same issue happened on another 7020... Seems to be either a problem with 7020 chip or something else in the firmware is causing this.
Mine is version 1.
About a month ago, I have sent a full backup image to Toysoft and when he installed it on his 7020, the same issue occured.
Cannot understand what the power suppply has to do to solve this. Box freezes only on streamrelay channels.
