- Changed the MANUAL description of the "Conditional Access" setup parameters
to reflect the actual "CICAM DVBn m" notation in the "Setup" menu.
- The new Setup parameter TrustedTransponder can be used to define which
transponder shall be used to set the system time (see MANUAL for details).
If you have been using the SetSystemTime option previously, you now MUST
select a channel that you trust to have a reliable time base.

SetSystemTime = 0 Defines whether the system time will be set according to
the time received from the DVB data stream.

1 = system time wil be set
1 = system time will be set
Note that this works only if VDR is running under a user

need to set the option TrustedTransponder to a channel
that you trust to transmit a reliable time base (not all
channels seem to have access to a correct time base...).
TrustedTransponder = 0 The frequency of the transponder that shall be used to
set the system time. The Setup menu will offer the full
list of channels, even if several of them are on the
same transponder. Also, when selecting a channel, saving
the Setup and opening the Setup menu again, there may be
a different channel listed here, since the first one
in 'channels.conf' that is on the given transponder will
be taken. Note that in order to set the system time from
the transponder data the option SetSystemTime must also
be enabled.
MarginStart = 2 Defines how many minutes before the official start time
MarginStop = 10 of a broadcast VDR shall start recording, and how long
