Roughly, the callback should be at the places where these two get called:

Good point. What if VDR wants to switch, but fails. Is it possible that
the channel change still fails after deleting liveSubtitle and
dvbSubtitleConverter? How does VDR itself handle this? Need to
If switching to a certain channel fails, VDR will notice that the
primary device no longer HasProgramme() and will try to switch to
a different channel.
If a call to MsgChannelSwitch(this, 0) was done on channel change, we
have to make sure that the corresponding call for the new channel does
happen, or - worst case - there's a call for the old channel again.
What I really see as a problem here now is that the first call to
GetDevice() may call a device's DetachAllReceivers() and the second
GetDevice() call may then decide to actually use a different device.
I'm currently considering giving GetDevice() another parameter:
static cDevice *GetDevice(const cChannel *Channel, int Priority, bool
LiveView, bool Query = false);

I'll release version 1.7.25 later today, so that all these changes can
