I'm trying to tune channels using DVB (digital video broadcast). I'm not trying to capture video from an external tuner or such. I can tune analog channels just fine using V4L but I am hoping that the DVB/QAM/ATSC drivers will allow me to tune unencrypted HDTV and digital channels from cable tv. I have the utilities (czap/dvbscan) but they require some initial data to get started. I don't even know if it's even possible to do this so I am also asking if anyone has done it first. I'm also curious if this works with satellite (DVB-S?)?
