From application point of view the signal strength information doesnt contain any useful data as long it's not standardized and reliable across all frontends. Therefore i decided not to use signal strength. Otherwise some frontends would not work. Signals without identifiers will not be removed, since some of them have their channel names inside EIT information or inside private data (i.e. Prmiere) and deleting these channels would make other users really unhappy. ;) Most of these channels are encrypted, so try to avoid them with -E 0 . But channels without video *and* audio will be removed instead. > [1] http://wirbel.htpc-forum.de/w_scan/index2.html > > ps.
