Confirm that. I noted this here about a month ago also on another
thread.

Could the CAMs be somehow initialized before VDR starts to operate
normally?

True. And there are multiple scenarios like this one that can arise.

Same here. Only problem still left is that if a recording is going on
and VDR crashes (or emergency exits...) for some reason the systems ends
up in a never ending emerg exit loop. That's because the CAMs are not
initialized before VDR starts to resume recording and therefore doesn't
get any data (video data stream broken) and issues an emergency exit.

This also kinda relates with the thread about Error handling vs. user
friendliness.
