Good reception on one device, completely different story on another device - same cable; different tuner sensitivity. It is *very* important to achieve *very* good signal reception with larger dish(DVB-S) and/or Yagi-Uda(DVB-T) - focal angle/directional gain. Try this one: dvbstream -f freq -o 8192 > full-mux.ts enough free disk space ;) mplayer -cache 8912 full-mux.ts (TAB-TAB-TAB…) or dvbstream -f freq -o vid aid tid pid > single-stream.ts cheers, poma
