Oh, I never saw that! That must be the moment where mythtv realizes
that the Encoder has "walked away"! Have to check if anything happens
right before that timestamp.

Yes, I'm making recordings with device, if it doesn't "walk away" it
records just fine!

/dev/video0 is my other TV-card, so /dev/video1 is the correct device
for this card.

I have a look at the logs again. Thanks!
