No answer to your question- in fact you're doing better than I am.. I can't get them to play at all..

Maybe you can help me: What file extension needs to be at the end of video clips for real player to lauch them? They are showing up as blank documents like some of the mp3's do..

When that happens to a downloaded mp3, I just shorten the name and add .mp3 and the icon changes from a blank document to real player icon and the it will launch. What should I do differently to the video clips so they will launch? What should the file extension be?

Thanks and good luck w/ your problem.
