When using 'real' video of a race, the time to find and decode a frame can be noticable when jogging the wheel to move frame-by-frame.
Suggested fix: When the user clicks on a marker in the video scrubber, locate the frame of interest and display it. In the mean while, locate and cache several frames on either side of the selected frame so they are immediately available when the wheel moves.
