If the TV will be connected to a cable or other type of tuner box, these features will not be usable since the tuning is controlled by the Set-Top Box. The program guides for some of these devices do have a feature that will switch the channel at the appointed time RCA's using program guides for over-the-air programming had this feature, but with digital boxes becoming commonplace, those features have begun to disappear. So, that brings up the question of how this person will receive the programming for the TV, will it be over-the-air, or via a box.
The subtitles feature (or closed captioning) is available on virtually all TVs now, so that won't be a problem to find.
