¿Qué van a echar a las 6 de la tarde?
No sé, pero esto es lo que puedes ver [a continuación / dentro de un rato / luego].
What is the the difference between these three options?
Which ones would refer to "next program relatively to now" and which "relatively to 6pm"?
I need two versions of answers; one which would say what is on tv in a moment from "now" and the other that would say what is on tv after 6pm.
