MythTV no longer scans channels from Setup Wizard
Once upon a time if you highlighted your capture card while setting up mythtv in AVWizard, it would scan channels for you, and you did not need to run mythtv seutp from computing. While fixing this, verbiage should be added to indicate that this is what should be done. I probably did 100 installs before even knowing it would scan if you highlighted the tuner as the next button persists regardless.
I have not seen this behavior since 810. Also often times schedules direct (from setup wizard) immediately insists there is a problem logging into the site. I can tell that it is not attempting to connect. Seems random.
