HELP!Can somebody please be so kind as to help me find the name of this movie?

I'm looking for this oldish movie i once saw as a child that i no longer remember the name.The way i vaguely remember It was about this family that included two kids,a mom and dad. The whole movie is about the two kids that had gotten i think a new magic tv remote and some how zapped them selves in to the tv so now they're in the tv and every time they change the remote they would walk in to a different channel. That's really all i can remember thank you in advance!
