So the Digital scanner doesn't fail per se, it just doesn't pick up most of the digital channels available. The same is true of scan, it seems to find only 1 channel when I know that I have access to 18. > > 4. Does digital tuning still work in MythTV despite the digital scanner > not working? Using the command line tools you linked I am able to tune to the channel that is found and watch it via mplayer. Let me know if you need anything else.
