EyeTV uses TV Guide for the EPG, but does not work with TVGuide.com
EyeTV has no affiliation with TVGuide.com at this time.
A TVGuide.com account is not an EyeTV Program Guide account.
EyeTV 3.1 has a separate, private connection to the TV Guide database, to provide a Program Guide.
Please sign up for a TV Guide account for use in EyeTV, via the EyeTV Setup Assistant. You can access the Setup Assistant from the Help menu, or the EyeTV menu.
