Comments

This function sets the preferred video renderer. The default value is ltmmVideoRenderer_VMR9.

LEADTOOLS will automatically try the assigned video renderer preference. If that fails, then LEADTOOLS will step down to an earlier version of the renderer, until all renderers are exhausted.

If you are on a system that supports VMR7 or VMR9, then the Legacy renderer is not automatically attempted unless the user explicitly sets Legacy as a preference. This prevents screen flashing on these systems.
