Welcome to the forum.
To rule out the file as part of the problem, can you give us the full specs. of that AVI file, both the Video and the Audio?
That is like saying "there is something wrong with my pickup truck and carrying a large load"
What brand & model pickup truck, and what is a "large" load?

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037?tstart=0
Report back with the codec details of your file, use the programs below
For PC http://www.headbands.com/gspot/ or http://mediainfo.sourceforge.net/en
For Mac http://mediainfo.massanti.com/
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line
above the video in the timeline, which indicates a mismatch between video and project
I captured the particular avi file using the DV codec. About 90% of the files in the project were captured in the exact same way and show no sync problems. The specifications for the file are Image size: 720 x 480, Frame Rate: 29.97 (Non-drop frame), Pixel Aspect ratio: 1.2121, source audio format: 32000 Hz -16 bit stereo. The only difference between these properties and those of the project is that the project's audio format is 32000Hz -32 bit stereo. But this change in audio has not affected any other file. There is no red line over the video in the timeline window. Does this information help? Please let me know if you need further information.
Does anyone have any solutions or suggestions for this issue? This is the only file that is affected with this odd issue. I have tried everything that I can think of.
source audio format: 32000 Hz -16 bit stereo.
That's a little strange, and actually out of spec for DV. You can have 32K sampling, but only at 12 bit resolution. You can have 16 bit resolution, but only at 48K sampling. To the best of my knowledge, all DV cameras will record in that way, and PP will only capture in that way. There's no way to get a 32K, 16 bit file out of a camera.
Which begs the question, where did you get these files that use the DV codec but don't seem to play right?
