No longer audio on .avi files when attempting to use Elements 9

Question

I have compiled 20 years of videos from family videos and converted them to .avi files.  I now want to edit these files into other smaller videos to give to my children.  I have Premiere Elements 9.  When I get one of these files using PE9 there is no longer audio on them. 
There is audio if I play them on Windows Media Player but no audio on Quicktime Player. 
I can edit in Windows Movie Maker but not in PE9.
The Quicktime Player states the following:
Format: Motion JPEG Open DML, 640 x 480, millions
Movie FPS 29.97
Playing FPS 29.97
Data Size 1.94 gb
Data Rate 8.67 mbits/sec
Normal Size 640 x 480 pixels
Current Size 640 x 480 pixels
I have a Dell Inspiron 530, 4.0 gb RAM, 32- Bit Windows Vista system.  Plenty of Hard Drive availability.
I purchased PE9 because I thought it would be superior to Windows Movie Maker.  Very frustrated.

Hi Bill,
The .avi file is a compilation of videos from multiple cameras from over the years.  There is no 1 camera.  That is why I am confused here.

What camera produced the MJPEG files, wrapped in the AVI container? The reason that I ask this, is because camera mfgrs. love to tweak CODEC's, and some take that tweaking to an extreme. If you have the utility disc, that came with the camera, it is probably best to install their particular version of the MJPEG CODEC. The Morgan, or the MainConcept might work OK, but having the exact version, from the camera mfgr. will get you as close, as is possible, and will save having to buy an MJPEG CODEC, that might not be perfect. Now, on that utility disc, one might have one of three possible choices: The MJPEG CODEC might be a separate installationThe MJPEG CODEC might install along with the camera's driverThe MJPEG CODEC might install with an included editing/cataloguing program (most common nowadays), and even if you do not use that utility, having the proper version of the MJPEG CODEC installed on the system, will get you as close, as is possible Good luck, and let us know if you have the utility disc for that camera.
