It does. The typical use case is that you pause live video or start
a recording with a timer, then start watching it while it is still
recording, so that you can skip commercial breaks. Then you get
interrupted while watching it. It would be very handy to push the
If it was a short interruption, you'd push any button to resume playback.
If the interruption was longer (such as your kid wakes up and you'll have
to put him back to sleep for a few hours), vdr would do the right thing
and shut down after finishing the recording.

I wouldn't be so sure about the majority of VDRs using FF cards. I
haven't seen any ad for an FF card, but I have seen many ads for cheap
USB DVB-T tuners. The trend is likely to change, given that decoding
MPEG-2 is no challenge to current PC hardware. But anyway, I agree with
you that this doesn't belong to the shutdown rewrite.

Hmm, doesn't the cDevice::Action() loop keep polling the device, even
though there are no registered consumers for the data? At least that
was the case last time I looked, around 1.3.38.

How can I check this? Using dvbstream or tzap while vdr is running?
Or from some file in /sys or /proc?
