When you're working on something which is going to be broadcasted on TV, then you have to turn on this feature called safe frames (click on the image above and look.. you can also press the ' button on your keyboard if using After Effects)
Everything outside the outer border will be cut off when shown on TV. Don't ask me why, that's the way things work when they appear on TV. So be safe and try to keep all the animations withing the action safe border.
If you're using flash, do a rough approximation of the title/action safe area on your Flash stage. Don't animate anything too near the edge of the screen.
Good luck.
