A new (just what I need!) MySky problem appeared yesterday: live pause & rewind no longer worked: they displayed a “this program cannot be recorded” error message, even when nothing else was recording (and on any channel).
I managed to fix this with a reboot (hold down ‘go back’ and ‘select’ on the front panel), but it’s yet another reason to avoid MySky for now.

I just noticed that live pause and rewind don’t work at all on the preview channels 0 and 25.

Mine was the same, removed the power plug from the rear for 10-15 seconds and re-inserted, all good now.
