Audio Drift with WAV file

I am creating several "books on CD" using my video camera and Movie Studio 6.0 Platinum edition. I record my audio on D8 and transfer it to my computer. I then delete the video, retaining the audio on the voice track. I use background music on the music track, and an voice introduction on the sound effects track. The music fades to a low level for the intro and then continues in the background for a while when the narration starts. When finished, I render it into a WAV file to burn onto a CD.

Everything matches on the work track, but after rendering, the music track starts to wander. The music fades out completely and the voice track comes in only after the music fades away...the music is suppose to continue in the background for about ten to fifteen seconds after the voice over starts. At the half hour mark the music is suppose to fade in under the background for about ten seconds and then come in full when the voice over stops. Instead the music came in about three minutes early. The brief introduction at the beginning and end do not appear to drift, only the music. Again, this all matched up on my work track but drifted wildly after the render into a WAV file. Any ideas?

One other thing. I've noticed that the timeline is also way off. It is suppose to end at one hour, which it does. However, the audio is about five minutes behind, so it just ends in mid-sentence at the one hour mark. Just to experiment, I also made it into a mpg file, nothing changes. I am stumped.

I seem to have audio drift in my renderings similar to you, although it seems more pronounced in preview mode.

I am wondering whether to tick the box for full render when creating this item (that is, force VMS to do the lot and not skip bits), the other thought I had is that the WinXP machine may have periods of "busy" when the render or playback is happenning, producing the phenomenon of slow audio.

For the latter, I intend to switch off the print spooler service and the NAV continuous checking. Will see how it goes.

It appears that my problem lies with the audio track FX that I am using...especially the Pitch Shift. When I remove the FX, everything goes back to its right length and synch. I have to finish this project, but later I plan to experiment and see what is up with this. Anyone else experience this when using the audio track FX?
