The TV Guide is only transmitted in countries that use DVB. Its normal to get no guide information in the US. Infact, this screen is hidden from North American users in the later 1.2 release to remove any confusion.
The channel names in the US are be available when you use digital ATSC, and on some digital cable networks. The names are never available for analog cable channels like they you've shown above. For analog channels it just has to make up a name for each channel - you can rename the channel manually though.
