- The pipe to the Dolby Digital replay command (option '-a') now closes all
unused file descriptors in the child process to avoid crashing when the
OSD is used (thanks to Andreas Vitting).
- Switched to the driver's new tuning API (VDR now requires a driver version
dated 2001-09-14 or higher).

VDR requires the card driver version 0.9.0 or higher
to work properly. You need to load the dvb.o module *without* option
'outstream=0' (previous versions of VDR required this option to have
the driver supply the data in AV_PES format; as of version 0.70 VDR
works with PES format).
VDR requires the card driver version dated 2001-09-14 or higher
to work properly.
After extracting the package, change into the VDR directory
and type 'make'. This should produce an executable file
