Usually, objects/clothing/hair don't show, if they were made when the EP playing of the creator, when he created the object, is not the EP you have.
For instance, I don't have Pets and Seasons - only Uni, NL and BV, and many of the outfits I download recently are not seen in the game, although they are seen in the Dlds folder.
You don't have to worry about that...

About the TV, I don't know. May be some hack, or downloaded TV, clashes with the default one.
