I built a VDR box a year ago; it worked;
For some reasons, I changed the motherboard and software.
Now dvbscan fails : I suspect the fact that the LNB is not powered.
My configuration
Fedora 8 x64_86 up to date Hauppauge Nexus dvb-s rev 2.3
There is signal, since the decoder works ok.
dvbscan fails, kaffeine too.
Thank you for your help
