Note 1: There is no guarantee that every frontend driver works
out-of-the box with every card, because of different wiring.

If you are using a Technotrend/Hauppauge DVB-C card *without* analog
module, you might have to use module parameter adac=-1 (dvb-ttpci.o).
5. The dvb_net device doesn't give me any multicast packets
5. The dvb_net device doesn't give me any packets at all
Run tcpdump on the dvb0_0 interface. This sets the interface
into promiscous mode so it accepts any packets from the PID
you have configured with the dvbnet utility. Check if there
are any packets with the IP addr and MAC addr you have
configured with ifconfig.
If tcpdump doesn't give you any output, check the statistics
which ifconfig outputs. (Note: If the MAC address is wrong,
dvb_net won't get any input; thus you have to run tcpdump
before checking the statistics.) If there are no packets at
all then maybe the PID is wrong. If there are error packets,
then either the PID is wrong or the stream does not conform to
the MPE standard (EN 301 192, http://www.etsi.org/). You can
use e.g. dvbsnoop for debugging.
6. The dvb_net device doesn't give me any multicast packets
Check your routes if they include the multicast address range.
Additionally make sure that "source validation by reversed path
lookup" is disabled:
$ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"
7. What the hell are all those modules that need to be loaded?
For a dvb-ttpci av7110 based full-featured card the following
modules are loaded:
- videodev: Video4Linux core module. This is the base module that
gives you access to the "analog" tv picture of the av7110 mpeg2
decoder.
- v4l2-common: common functions for Video4Linux-2 drivers
- v4l1-compat: backward compatiblity layer for Video4Linux-1 legacy
applications
- dvb-core: DVB core module. This provides you with the
/dev/dvb/adapter entries
- saa7146: SAA7146 core driver. This is need to access any SAA7146
based card in your system.
- saa7146_vv: SAA7146 video and vbi functions. These are only needed
for full-featured cards.
- video-buf: capture helper module for the saa7146_vv driver. This
one is responsible to handle capture buffers.
- dvb-ttpci: The main driver for AV7110 based, full-featued
DVB-S/C/T cards
