Videos apearing in active movie window

[Jeff]

I have seen this once before with a different file format. With the default Windows 7 codec a separate window opened. Installing a 3rd party codec fixed the problem.

In that case the file was high resolution and our guess was that the default codec did not support decoding to RGB if the video size was above a certain threshold.

Try installing other 3rd party codecs to see if that works for you.
