function always has to accept the entire data block immediately and there is
nothing that could be reasonably done in case an error occurs in one of the
cAudio objects.
- Now checking the driver's DVB_API_VERSION in dvbdevice.h. Since VDR now requires
a driver dated 2002-11-01 or later the MIN_DVB_DRIVER_VERSION_FOR_TIMESHIFT and
DVB_DRIVER_VERSION stuff has been replaced with DO_REC_AND_PLAY_ON_PRIMARY_DEVICE,
which can be used to disable simultaneous recording and replaying on the primary
DVB device in case there are problems with this.
