An up to date Quicktime Player running on XP Pro gave me a message when I tried to play a Quicktime tutorial that I have. The message was to continue to Quicktime Components in order to play the video. There were about ten choices from that page, but no indication which I should install. I installed a few but the video still does not play. All other Quicktime videos on my PC open fine. Any suggestions on how to find what I need to add to or modify Quicktime Player with? The message only appeared once. I don't get the message pop up when trying to play the Quicktime tutorial video anymore. Thanks.
