I'm pretty much a noob when it comes to video editing and I need a little help.
I've got a video clip with sound I want to mute and I've got an audio clip that I want to match the video to. When I add the mute effect to the video it does not mute it. When I separate the audio from the video and add mute it still does not mute. Also, I can't figure out how to get video clip and the audio clip to play together. I saw somewhere else that you're supposed to add the audio clip to the video but I can't figure out how to do that. I'm running Ubuntu 7.10, if that makes a difference.
I've tried darn near every video editor available in Linux and this is by far my favorite. I just need to figure out the sound thing. Thanks.

Deleting the sound after it was separated sounded like a good idea. But it didn't work. I just noticed it's still listed as an .avi, maybe that's why?
Here's a screenshot.
