Thank you guys for your support ! Olliver, thank you for your commit I tested it and the parsing 1) is now good. However problem 2) is still there : no services are found at the end of the scan. I mean when doing : scan dtv-scan-tables/dvb-t/fr-All the end result is : "ERROR: initial tuning failed dumping lists (0 services) Done. " Digging further I think the problem is due to FEC, QAM and Guard Interval parameters consistency. Indeed in France it seems there are 2 schemes for DVB-T services depending on where you live (I'm not quite 100% sure as I could only find very few official & reliable information) : FEC 3/4, QAM64, Guard Interval 1/8 FEC 2/3, QAM16, Guard Interval 1/32 Whereas in the file we have : FEC 2/3, QAM64, Guard Interval 1/32 However I think this scheme may be OK depending on your HW frontend tolerance. Unfortunately it doesn't work with my Hauppauge NOVA-TD-500. I propose 2 options : A) rely on the the AUTO capability and use FEC AUTO, QAM AUTO, GI AUTO in the frequency file (please refer to attached file fr-All-optionA) B) double the file with both schemes for each frequency (please refer to attached file fr-All-optionB) : the drawback is that the scan is twice longer. I sucessfully managed to scan services with both A & B. I've attached both tests outputs for your reference. => But I only have TV channels with the first scheme in my area. Do you have an opinion about A or B ? Thank you.

I patched it to fix the casing as suggested in the e-mail and pushed it upstream. Can you please test it?
