===== Sundtek DVB-C Tuner =====
==== Installation ====
<code bash>
ssh -l root <VDR-IP>
cd /root
wget http://www.sundtek.de/media/sundtek_netinst.sh
chmod +x sundtek_netinst.sh
./sundtek_netinst.sh
/opt/bin/mediaclient --dtvtransfermode=bulk -d /dev/dvb/adapter0/frontend0
# Reconnect Tuner #1
/opt/bin/mediaclient --dtvtransfermode=bulk -d /dev/dvb/adapter1/frontend0
# Reconnect Tuner #2
#
# VDR erneut starten wenn DVB-Tuner Treiber geladen sind:
echo "device_attach=service vdr restart" >> /etc/sundtek.conf
</code>

===== VDR =====
<note important>
Auf keinen Fall die automatisch generierte Kanalkonfiguration (''channels.conf'' für vdr) aus dem Kabel Deutschland Forum verwenden - die Parameter für die HD Sender der Öffentlich-Rechtlichen sind fehlerhaft und bringen den VDR regelmäßig zum Absturz (data stream broken -> emergency exit).
