Extremely Small Text Video

[2brian0]

Forgive me if this has already been covered but I've tried searching here and multiple other places for the answer.

When I receive a video or slideshow text, it is extremely small and only appears in the center of the screen (hitting the maximize button at the bottom of the screen does nothing). Is there any way to enlarge this? Here is a screen shot for reference. I apologize about the picture but most video texts I get are way too inappropriate for a public forum and this was the most PG one I could find. When I receive picture messages, they take up the whole screen.
