Flv as thumbnail

I trying to make a small video gallery and thought to use the .flv’s as buttons for the scroll bar. then have them tell a MC to goto a frame to play the full size flv. Going to use a flv as a thumbnail in stopstate so to just have the image. Just wondering is better making thumbnails and having them or stopstate or is this about the same bandwidth. Considering that the flv’s will have to be loaded anyways.

which would be the better grabbed image or stopped .flv

Any thoughts on this would be appreciated

many thanks
