I have used every player I have. I have tried on the files too, they are just being made wrong for some reason. The players I have will play video files that are completed, but not the preview files that are created for them.
I'm using version LW Pro v 4.12.6 (latest)
Media players I have tried are Windows Media, Nero Showtime, CyberLink PowerDVD, WinAmp, Acer Arcade, and some xvid one that I no longer have here.
I'm sure it's just messed up. Maybe if I get an earlier version of LW.
Here are some screenshots:
