What player are you using? Do you get an error message when you try to play them? Your player might need codecs.
Did you preview the movies while downloading, to make sure that they were ok?

Always make sure to check a movie with Bitzi before download.
How to use Bitzi

Check out the link below...there are further links to codec packs & also VLC player. It's free, has codecs installed & will play most things:wink: If you'd like to try it, choose the nearest mirror for download
Codecs & VLC

To launch a movie with VLC if you use Windows, you'll have to do it from within your saved folder rather than from within LW. Go to your LW library, click on Saved Files then click Explore...saved folder opens & you can launch from there!
