There seems to be a 200ms lag on sound when I use my blue-tooth speakers (1/2 meter distance) in windows 7 (belkin 6.0.1 vista drivers.). Is there a way to reduce this?
Some video players like VLC can compensate for the Bluetooth lag by advancing the audio ahead of the video. In VLC if you press "J" while the video is playing you can adjust the audio "delay" to -250ms. There's a preference to set this permanently.
