Go back to your original Vegas project and be sure that your channels are mapped properly. By default, each track is mapped to all five speakers. Turn off all but the correct one on each track and re-export. If you re-export it to the same file name as before, you shouldn't have to re-do all those edits in Womble.

Hope that solves it for you.

Hmn, I thought I had the configuration right about my surround sound, but it seems it was not right. I have muted all channels but one, and I can still hear it in every speaker.
Here's a screenshot of my configuration:

I rendered as a surround sound.

Can you tell me what I have done wrong?

EDIT Oct. 8th:
I noticed I only heard the center channel, the other channels didn't play. I tested my surround sound on my computer, and it works.

In Vegas, with each channel I had clicked on the speaker that it should be. But because of this, somehow I couldn't hear it.

I have dragged each orange figure to each speaker, and then I can hear it.

But after with rendering, I play the AC3 with Media Player Classic, and I hear the same things in each speaker, which is not the case when I preview the file (before saving) in Vegas.

I really don't know what to do...
