Dave, has the issue with 7flix anything to do with the rebooting issue or is that something separate? I am pretty sure that I didn't tick the 7flix box on my account, I haven't heard of this channel before and haven't manually scheduled any recordings for it - maybe one of my series recordings made the reservations you mention. I don't have any way to check what the reservation was/is that I can see.
Back to the rebooting issue. This is still occurring on both my recorders whenever I enable ICE. If disabling ABC2 is the suggested solution, that is unacceptable to me as I have a 6 yo daughter and that is the only channel we let her watch.
I still do not understand why this problem has suddenly started happening after so many years. If, as it would seem, something has been changed at your end why is it that the system cannot be reverted to it's previous working state? As it is I cannot enable ICE for fear that the rebooting will continue/reoccur and I will miss recordings - so I am scheduling my recordings manually.
