Bug Description

1) Ubuntu 10.04 beta - Guest OS on Virtual Box with Windows 7
2) Ubuntu Software Manager
3) OpenShot 1.1.1

A video playing in the preview window is slightly re-scaled and shows gray vertical bars at each side of the image compared to the paused status.

Figure 1 shows a screenshot while playing (note the gray bars at each side of the image), Figure 2 shows an screenshot while paused at the same time instant, and Figure 3 puts both together. In the right side of the figure we can see that both don't have the same width.

This occurs systematically with three video types I have tried, a wmv file, an avi file and a openshot generated mpeg file, as follows:
