i have the new sony google tv NSZGS7, it was one of the 500 pre-released at google i/o. i am in toronto canada. the box has never showed my cable channel listings in the tv and apps section, and now that the actual device has been unofficially released in canada, i am still unable to see the channel listings on it. is there something special i have to do to get the channel listings to show or is just picking my cable provider and box all that is necessary? any help would be greatly appreciated.
