I'm a bit puzzled: 'volume', are you talking about audio?
Most FLV files have full motion video as well as audio. Think of a Television segment. That can be dropped into a Captivate project if it is in FLV format.
If you play it, you not only see the people talking but you hear them as well. The audio exists inside the FLV file and not the Captivate file.
What I'm understanding of the post is that if they were to play the FLV all by itself, the volume is acceptable. But if they play it from inside Captivate, something about playing from inside Captivate causes the audio volume of the inserted video clip to be reduced somehow.

The FLV I am using is a testimonial video. I am using one of the default skins (Clear Skin 3) which has video controls and a volume slider. When Captivate plays the video, the volume slider defaults to 50%. I need to change the default volume limit if possible.
