But wouldn't you also need an option to delay video by a frame period for cases where audio is already too late. Or is the assumption that the synch problem is always caused by delays in the video chain? gary =20 -------------------------------------------------------- =20 This email message and any files transmitted with it contain = confidential information intended only for the person(s) to whom this = email message is addressed.
