[Bug 430595] [NEW] scan from dvb-apps fails when using diseqc commands

[Steven Ellis]

Public bug reported:

Platform is Ubuntu Jaunty or Mythbuntu Jaunty

dvb-apps - 1.1.1+rev1207-4

When using the scan command to interrogate multiple LNBs connected via a
diseqc switch the scan fails.

A clean copy of the source from linuxtv.org works as expected - linuxtv-
dvb-apps-1.1.1.tar.gz

Usind the following scan file D2.aurora
# Optus Aurora Transponder on Optus D2 satellite  
# freq pol sr fec
S 12407000 V 30000000 AUTO
S 12448000 V 27800000 AUTO

The Optus D2 LNB is connected via port 4 on the LNB which is selected
via "-s 3"

/usr/bin/scan -5 -l 11300 -s 3 D2.aurora
scanning D2.aurora
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12407000 V 30000000 9

Done.


Running the same scan via a clean build off the vanilla source works as expected
