I get following error when running w_scan: $ w_scan w_scan version 20130331 (compiled for DVB API 5.9) guessing country 'RU', use -c <country> to override using settings for RUSSIAN FEDERATION Country identifier RU not defined. Using defaults. scan type TERRESTRIAL, channellist 4 output format vdr-2.0 output charset 'UTF-8', use -C <charset> to override Info: using DVB adapter auto detection. main:3228: FATAL: ***** NO USEABLE TERRESTRIAL CARD FOUND. ***** Please check wether dvb driver is loaded and verify that no dvb application (i.e. vdr) is running. On the machine with 3.10-2-686-pae kernel w_scan works fine with the same adapter.
