Distorted Audio after Rendering

I have the Screenblast version of Movie Studio and am using it for the first time. I rendered my project and the audio was distorted and sounded clipped. I have tried rendering twice with the same results. The project is a wedding video that is 2 hours 13 minutes long.

The first time I rendered it took 24 hours and the audio was distorted. I readjusted to audio levels on the track and to the sound card, I had them too high the first time and rendered again. The render took 40 hours plus and the audio was distorted again. I did one thing with the audio in both renders which could be a problem. I only fed the audio to the left track when I digitized. In the first render I panned the audio 50% to the right, in the second render I centered the pan control and rendered the audio in mono. In the first render, the waveforms for the audio were nomal and on both channels, on the second render, I had a mono track only with normal wave forms which indicates that the audio went where I wanted to send it. The video has graphics in all the frames for the Ist hour and 20 minutes if the matters other then render time.

The first render was to DVD and the second was to hard drive. Both renders were at DV video rate as an avi file.

I put the rendered file into a new project and tried to copy new audio files, but that audio was also distorted, when inserted into the timeline.

Finally the video would play in the windows player only to 4 minutes 42 seconds and at fast speed in the player and in the Screenblast timeline after rendering until I rebooted the machine.
The machine is a Dell 3000 with 3 Ghz Hypertreaded Pentium, 512 Meg of memory and two 80 Gig harddrives.

I would be thankful for any help or ideas on what I am doing wrong or have set wrong or what I can do to solve the problem.

One thought is that it has something to do with how you captured the sound (and video) in the first place. You said you did things to the audio when you "digitized": What was the original source format? What did you use to digitize it? Did you wind up with a single .avi file, or did you wind up with an audio file and a separate video file?

Is the audio distortion intermittent or is it the same throughout?

I used a Laird Inertia Analog to DV convertor via firewire to digitize analog 8 millimeter video which created a DV-AVI file. I was able to edit the audio separate from the video. The audio also sounded fine when editing. The distortion is throughout the rendered file. There were lot of JPeg graphics in this video plus text. For 2/3 of video there were two layers of graphics over the captured video. I did do a short preview render over a video/no graphic section and it played ok.
Thanks

Hmmm... the closest thing I've seen to this is I once did a semi-long render (not anywhere near 2+ hours of video) and for some reason the audio was completely missing. I did the render again and it was OK. Never could explain it.

The fact that the audio was fine when you rendered a snippet makes it even odder.
