Using eyetv hybrid connected to my cable tv provider, EyeTV4 8526, later 8527. App installs, finds my existing (from using EyeTV3 on MacBook Pro 17" late 2011 and macOS High Sierra 10.13.6) EPG subscription and accepts the license I received at purchase of EyeTV4. It displays channels and a TV program, but I just receive a message saying no signal or such, no matter what program I attempt to view. On a hunch I went back and had the app auto-tune all cable channels. It displays "One moment please" and seems either never to start or never to finish after almost one hour.
Does anyone know how to completely remove the EyeTV4 app? I'm wondering whether vestiges of EyeTV3 are lurking after I migrated my account from the MBP17.
