How do I know Smart Play is working properly?
Smart Play may drop back to standard media playback if it can't find the component you specified for
a media format, or when it encounters an unrecognized format.
You can see that Smart Play is working by playing a video, right-clicking on the video area and under
the "filter properties" sub-menu, you should see a "Source File: Smart Play Graph" (or "Source File: Customized Graph" in older versions).
