If you have a motor and you are able to automatically peak satellites, the only thing missing is a program to find all the signals automatically, including the ones which are turned on and off in a matter of minutes. Just google for *blindscan* (and maybe my name) to find a utility I wrote years ago and abandoned after failing to get the corresponding mt312-autosymbolrate kernel patch integrated. Next step, automatically upload found signals on some site, maybe including a frame from the received video stream and let users comment/moderate interesting ones on a sort of forum. :-) Hmmmm, feeds...
