- The device /dev/video is now opened only if necessary (to GRAB an image),
allowing other programs (like 'kvdr', for instance) to use that device.
2001-11-10: Version 0.9.9
2001-11-24: Version 0.9.9
- Changed version numbering scheme.
- Fixed several channel definitions in 'channels.conf' (thanks to Thilo
Wunderlich).
- Added MPEG audio support for DVD (thanks to Andreas Schultz).
- Implemented DVB-T support (thanks to Dave Chapman).
- Removed the range limits for the Frequency and Srate parameters of channel
definitions.

Running VDR with DVB-C (cable) or DVB-T (terrestrial):
------------------------------------------------------
VDR automatically recognizes if the DVB card in use is a cable card.
The only things that needs to be different when using digital cable
is the 'channels.conf' file. The distribution archive contains a default
'channels.conf.cable', which cable users can rename or copy to 'channels.conf'
in order to receive cable channels. The format of this file is exactly the
same as for satellite channels (the fields containing "Polarization" and
"Diseqc" data are ignored in case of DVB-C).
VDR automatically recognizes if the DVB card in use is a cable or a
terrestrial card. The only thing that needs to be different when using digital
cable or terrestrial reception is the 'channels.conf' file. The distribution
archive contains a default 'channels.conf.cable' and 'channels.conf.terr',
respectively, which users of such cards can rename or copy to 'channels.conf'
in order to receive digital cable or terrestrial channels. The format of these
files is exactly the same as for satellite channels (the fields containing
"Polarization" and "Diseqc" data are ignored in case of DVB-C and DVB-T, and
the "Frequency" is in kHz in case of DVB-T).
You can even use a mixture of DVB-S, DVB-C and DVB-T cards in the same system.
All you need to do is to put all the channel definitions into one big
'channels.conf' file and set the 'Ca' parameter of each channel to the number
of the card that can receive it.
