It's hard to say, because it's not likely that the video your helmet cam produces is DV-AVI. It's likely using another codec which, in Premiere Elements, means that it's impossible to predict how it will behave.
The easiest way to see which codec your video uses is to open it in Windows Media Player and go to File/Properties.
It will likely require a conversion to the more standardized DV-AVI before you'll be able to edit it with predictability and stability in Premiere Elements.
the codec is: mpeg-4 Video (xvid), 720x480, 30fps audio: Mpeg Audio layer 1/2/3 mpga, mono - Will I need to convert this?
Thanks again, Ted
Yes, you will need to convert xvid (a display only codec) into DV AVI Type 2 with 16bit 48khz sound to be able to edit in ANY flavor of Premiere

Xvid (or DivX) are delivery-only CODEC's and are not meant to be edited. Even with them properly installed, it is unlikely that any Adobe NLE can edit that footage. I would definitely convert, and NOT try to use the Xvid.
Now, CyberLink's PowerDirector does a better job with Xvid, or DivX material, so that might be an option.
