Hi, I'm new to my Blackberry. I copied a movie to the devise and it plays fine but it's in a small square in the middle of the screen. I select "full screen" and it removes the tool bar on the top and bottom but the video size doesn't enlarge. Any ideas on why it won't or how to get it larger? Or does it never play video on the whole screen?

I have the same issue...is there a way to fix this??

I used to have the same problem. If you are viewing a video on youtube and it has HQ (high quality) vs. Normal, click on HQ. It will allow you to view a full screen video, ten times better than the little square you are seeing. I just discovered it after 7 months of Blackberry!

Have you checked for possibilities in your settings menu? Also what is the movie format?
