Unable to start playback of second video file to using player.exe

When you have multiple video files opened with the demo player application, starting a different video file doesn't always work correctly.

Steps to reproduce:
1) Open demo player application.
2) Open two different files so they appear in the file list
3) Double click first file - video plays
4) Double click second file - video screen goes black, and status shows "Loading". Video does not start correctly.

This scenario works ok if you press "Stop" before double clicking the second file to start. If you don't press "Stop" you, the second file never seems to get past the Loading state.

The same scenario allows the second file to be played correctly on 1.1.1
