 The \fBchannel\ ID\fR is used in the \fItimers.conf\fR and \fIepg.data\fR

+If a channel has both \fBNID\fR and \fBTID\fR set to 0, the \fBchannel\ ID\fR
+will use the \fBFrequency\fR instead of the \fBTID\fR. For satellite channels
+an additional offset of 100000, 200000, 300000 or 400000 is added to that
+number, depending on the \fBPolarization\fR (\fBH\fR, \fBV\fR, \fBL\fR or \fBR\fR,
+respectively). This is necessary because on some satellites the same frequency is
+used for two different transponders, with opposite polarization.
