kdenlive - Rendered video shows as just black with audio!

Hi,

I created a project using a title and an imported mpeg clip that has video and audio. While in kdenlive, the "project monitor" properly shows the title for 5 seconds and then plays the clip. However, when I render the video as an mpeg, it's just a black screen with audio starting after 5 seconds! What might be wrong?

I didn't find the right solution from the Internet.
