OK.
I've reworked the MPC and my video.
I machine tested the MPC to assure it works properly as well!
The 61.2 MB AVI lesson link is:

I increased the number of tabs and kept the process simple for the user to apply various lengths as needed. Watch the AVI lesson to make sure you understand the process, and avoid traps, and know how to get out of trouble.
