It would greatly improve usability. It is possible. Not sure how much efforts it would take. Could you please send me, in priv, a capture of ~30-60 seconds of a recent DVB-T2 channel in Germany with those fields, and the corresponding output from w_scan, for all channels at the same frequency? I'll use it to test it with my RF generator here, and see if I can tweak dvbv5-scan to produce the same output. The syntax to capture the full MPEG-TS is: $ dvbv5-zap -P -o channel.ts -t 60 scan_file.conf Even 60seconds produce a big file, so you'll likely need to store somewhere (like Google Drive) and send me a link to it. -- Thanks, Mauro
