dvbstream seems to not work with dvb-c

[Hadmut Danisch]

Binary package hint: dvbstream

Hi,

I tried dvbstream with my dvb-c card, but it never produces any output, it always issues the same error message "ERROR tuning channel":

% dvbstream -c 0 -quam 64 -f 458000000 -s 6900000 -o -v 102 -a 103 > /tmp/ausgabe

Latest version available from http://www.linuxstb.org/
Tuning to 458000000 Hz

ERROR tuning channel
: Invalid argument
dvbstream will stop after -1 seconds (71582788 minutes)
Output to stdout

the symbolrate is wrong as well.

Furthermore, the package seems to be incomplete. I found several hints that there is a program ts2ps to convert mpeg transport streams into program streams, but it is missing.

Linux kernel 2.6.33-rc5 may help you.

It contains the following comment:

Magnus Horlin (1):
      V4L/DVB (13748): [Mantis/VP-2040] Add support for VP-2040 (TDA10023 frontend based)

(V4L stands for Video for Linux).

Status changed to 'Confirmed' because the bug affects multiple users.

HI, also getting this error while trying to tune to C-BAND freq with dvbstream with DVB-S card

note, vlc tunes perfectly to this same frequency on any of the cards in this machine

i asked the developer for help, he told me to use "qam" switch (not "quam") and frequencies in KHZ. the -a -v switches are for older dvb cards so just add the pids to the end of the command..

given this information dvbstream also works for me with dvb-c:
