I needed an attenuator on Mendip UK before the transmitters power increased, now I can't get it work at all. Legacy applications/utils tested so far with 3.2/next on DVB-T on other adapters. scan okay use -5 option increases time out helps w_scan okay use -F option increases time out helps dvbscan fail Unable to query frontend status me-tv okay kaffeine okay VLC okay mplayer dvb:// okay VDR okay mumudvb okay zap okay -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
