w_scan is an application that greatly simplifies the task of scanning for DVB-T and DVB-C channel information. Winfried Köhler’s w_scan is special because it does not require any region-specific initial transponder data for operation. It will create configuration files for VDR and Kaffeine.

root@ubuntu:/usr/local/src# ln -s w_scan-20070909/ w_scan
Build the application with the following two commands:
root@ubuntu:/usr/local/src# cd w_scan
root@ubuntu:/usr/local/src/w_scan# make
root@ubuntu:/usr/local/src/w_scan# cp w_scan /usr/local/bin/
