for pointing out that an empty EPG event means there is currently no running event
for advance information about the use of the standard component descriptor for AC3
(stream=4) on the German ARD channels

@ -5762,12 +5762,17 @@ Video Disk Recorder Revision History
- Increased the time between checking the CAM status to 500ms to avoid problems
with some CAMs (reported by Arthur Konovalov).
2008-04-19: Version 1.7.1
2008-05-01: Version 1.7.1
- Adapted the tuning code to the new DVBFE_SET_DELSYS API (thanks to Reinhard Nissl).
VDR now uses the driver from http://jusst.de/hg/multiproto_plus.
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Removed obsolete $(NCURSESLIB) from the Makefile.
- Implemented handling the standard component descriptor for AC3 (stream=4), as it
will soon be used by the German ARD channels (thanks to Michael Pennewiß for
advance information about this change). The previously used "Premiere pseudo
standard" (stream=2, type=5) still works, but has apparently been wrongfully used
by broadcasters from the beginning.
2008-04-19: Version 1.6.0-2
