show only a certain kind of program, for example, cooking shows.

then select "Choose Filter." When the list of categories appears, select "Lifestyles,"
then select the sub-category "Cooking." Display Options appears again and "Filtering"

"Filtering." Press RIGHT arrow to turn filtering off. Select "Done changing options."
Your Program Guide shows all of your channels once again.
