This is strange as I had this when first setting up, it thought my Hisense TV was a Vizeo. I am not sure if your TV is a Hisense. But I changed it straight away and it doesn't reset for me.
Just a hunch, try changing the 'Standby power consumption' under 'Settings' > 'System' to Fast start. See if that makes a difference.
Just thinking Active start or the eco setting may actually cause the box to forget remote programmes.
Thanks
