And this tackles another small problem: I think that VDR doesn't delete
any channels from the channels.conf in any case. So outdated channels
have to be removed manually. Has there been an attempt to offer a
functionality that VDR makes a note of those channels that get the line
"frontend timed out while tuning to channel X" in the syslog and offers
those channels for manual deletion via the OSD in a special OSD page
called "Outdated channels"?

There's currently no 'official' method to track down channels that are no longer announced. There's a trick however: Modify your channels.conf so that all channel names start with [outdated], then start VDR and wait for a full transponder scan to finish. All existing channels will be renamed back to their proper names, and all remaining [outdated] channels can be dropped after some grace period.

I use a more advanced variant using a small patch and a plugin, both currently not publicly released: The patch tracks a 'last seen' timestamp to all channels, where 0 means 'not seen since VDR start'. A matching plugin holds a second channel list and periodically syncs with the regular channel list, with the additional info 'first seen' and 'last seen' tracked persistently across VDR sessions. Also, the plugin renames channels that are gone for some time so they can be identified and deleted.

This has however two downsides: First, a VDR that hasn't been running for some time will instantly mark all channels gone, and the same thing happens if a source is temporarily unavailable - for me, DVB-T is regularly not plugged, so all DVB-T channels are usually marked as gone.
