Bug Description
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-
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"

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