@ -1619,3 +1619,8 @@ Video Disk Recorder Revision History
- Fixed a small glitch when switching channels (thanks to Dennis Noordsij for
reporting this one).
- Fixed handling multiple 'CaCaps' entries in 'setup.conf'.
- Group separators in 'channels.conf' may now be given like ':@201 My Channels',
where '@201' indicates the number to be given to the next channel. This can be
used to create 'gaps' in the channel numbering (see 'man 5 vdr'). BE CAREFUL
TO UPDATE YOUR 'timers.conf' ACCORDINGLY IF INSERTING THIS NEW FEATURE INTO YOUR
'channels.conf' FILE!

Group delimiters may also be used to specify the number of the next channel.

The given number must be larger than the number of any previous channel

A \fBchannel definition\fR is a line with channel data, where the fields
are separated by ':' characters. Example:
