The Accusoft Mjpeg codec

when I use Mainconcept Totalcode 3.1 I can open a mjpeg .avi file using the Accusoft Mjpeg directshow filter only if previously I have install LAV Splitter

If I uninstall LAV splitter, Totalcode cannot open my mjpeg .avi file

I would not risk that another installation or another program go to change the default decoder for MJPEG avi files (avi video files that have the tag "MJPG") so I would like do a .reg or a batch file (that I put on boot of windows 8.1) that force the use of my preferred codec and no other codec. Is it possible also without keep LAV Splitter? thanks
