It can have been from the fact that my system has usually used ntp time 
updates and I had vdr time adjustment on just for testing purposes and 
forgot it on. ;)

Possibly the ntp time is way off from the channel times? Wouldn't be 
surprising imho.

Looks like I setup my log rotation to keep quite a clean schedule on the 
host and previous restarts informations have gotten the /dev/null 
treatment. So I can't get that info back right now and I would prefer 
not to change it back to previous setting until during weekend when I 
can do testing without getting complaints from other viewers of the 
channels. ;)

Looks like yesterday evenings restart while recording started produced 
different issues:
