Okay...

I combined two videos to make one big video, and then I muted the sound that was associated with that video.
I then added background audio to the project, and everything is the way it should be except that when I say "output as", I get no audio.

How do I get the muted video + the background audio I added all together into one video?

Thanks!

What program from the suite are you using for your project? I hope its Videowave.
Do you get the audio when you play in Videowave?
Be a bit more specific in what you did exactly

I'm sorry... I was in a hurry when I posted.

1) Yes, I was using videowave for everything.
2) Everything was fine videowave, the problems happened when I tried to convert it to a different format.

1) I had two HD videos with muted sounds that I combined through videowave.
2) After combining two, I added background music to the whole thing.
3) After trying to ouput it to a high quality mpeg video file, I get video, but no audio.

Thanks!
