I had a hard freeze yesterday evening. After reboot everything is fine. I never tried out to let live TV run overnight but I noticed that during live TV watching the device´s temperature increases. It´s not getting really hot but much hotter than watching a movie from NAS.
But I just touched from the outside.
Could be interesting how hot it is directly on the chips.
I think the heat will be a problem in the future regarding lifetime of the box.
