Comment 4 for bug 1013035

As this issue is based around indexing frames, it is important for us to be careful that every frame is included. To make this easier I have attatched an image sequence with the first and last frames clearly marked.

The image sequence is 80 frames long. The first frame marked with a large "1" and the final frame marked with "80".

On PAL this sequence should be 3.2 seconds long (80/25).
On NTSC this sequence should be 2.67 seconds long (80/29.97 then rounded to 2 decimal places)
