It could be that your AVI uses codecs that aren't editable. There are, after all, thousands of variations of AVIs.
Open one of your AVIs in Media Info and note the resolution, frame rate, audio and video codecs and video writers listed.
It's the first time I use MediaInfo and I am a bit lost. Here is what it says about the file, but I would be very surprised if I Premiere Elements would encode in a format it cannot decode. The "Add Media - Webcam" feature must have been designed with the aim of editing the shots in Premiere Elements.

This is a pretty standard DV-AVI, so you should have no problems editing it in Premiere Elements, assuming you've got Quicktime installed on your computer.
Although you don't say which version of Premiere Elements you're using. Since version 11, the program will automatically set up your project to match your video. Prior to that, you needed to do it manually. Go under the Edit menu and open the Project Settings/General page and ensure that your project is set up for 720x480 29.97 fps video.
If you are still having problems, it could be that you did not let the program fully conform your file before you started editing it. Usually conforming video happens rather quickly -- but in your case, you've got a 38 minute video, so it may take several minutes for the program to fully conform it.
You can watch the progress of the program conforming your file in the lower right corner of the program's interface.
I have Premier Elements 14.1, so the project should adjust automatically.
And I do not think it is a question of letting the program enough time before editing the video : when I "import" it through "Add Media - Files and folders" it says the video is only 2'38".
On the basis of the replies to other questions, I downloaded Handbrake and transformed the .avi into a .mp4 file. It plays the full length in Premiere.
It is still amazing to see that an .avi file recorded in Premiere does not play correctly in Premiere ...
I still think it's a matter of not letting the file fully conform the first time you loaded it in the program.
