You folks experimenting with Composite video out should also try DLNA. I don't have a DLNA hardware device such as a PS3 or an XBOX, but WIN 7 supports DLNA ...
... So I easily got DLNA working wireless (Over WiFi) to my WIN 7 Media Player. Using AllShare on the Captivate, I am able to access my media (video/music/photos) from my WIN 7 PC and play on the Captivate, and I can also play the same type media from my Captivate to the Win 7 Media Player. DLNA on the captivate supports 720p video.
