Force VDR to save channels.conf

Hello,

I have a headless vdr server - witch is just used for streamdev and xbmc.

I would like to update my channels.conf as it is pretty outdated right 
now....

I have set the following in setup.conf and vdr is now searching and is 
detecting new channels.
UpdateChannels = 5

How ever - when I restart VDR the changes are not getting saved to 
channels.conf.

What can I do to make it save channels.conf?

I think that last time I had to do this I had to connect via VNC and the 
vdr-ffnetdev plugin to get the OSD and to "press" the power button to 
make it shutdown and save the changes...
Is there an easier was to do this?

Thanks, Artem

svdrpsend hitk power - also works over the network - if configured for
that.

Check the syslog. There might be a plugin not cleanly shutting down,
making the vdr abort it's shutdown sequence causing it's settings to not
be saved.

Actually a forced save of setup.conf, channels.conf, and epg.data
would be a good feature to have. You should msg Klaus and see if he
agrees.

Unless things have changed very recently, VDR doesn't save channels.conf
on shutdown.

It only saves it
a) Immediately after user manually modifies channels via VDR
b) 10 minutes after automatic channel update

I've been hit with this many times as well, so I'd suggest to change VDR
so that it saves automatic channel updates on exit as well. Suggested
patch attached (only compile-tested, so actual testing is needed).

I'm afraid it's not that simple.

channels.conf and timers.conf must always be in sync, because timers
reference channels. Plus you need to have a lock on the Channels list
to prevent any changes from other threads while saving the list.
See the main VDR loop under "// Handle channel and timer modifications":

           if ((modified || timeout) && Channels.Lock(false, 100)) {
