If for some reason this app doesn't rename MU back to SU you can use this script to fix it.
Just download the script to the root of your SDcard and then run this in a Terminal Emulator (Available in Market):
Code:
sh /sdcard/googlevideo.sh
It'll first tell you if SU is currently named SU or MU. Then depending on what it told you run the following command:
If it said Root is SU then you're root should be fine,
If it said Root is MU then run:
Code:
mu sh /sdcard/googlevideo.sh
Root should now be repaired. If you have any questions or problems please PM me.
Notes: This script is designed to Autodetect where SU is and whether you're running the script as Root or not. If you aren't Root it'll inform you whether you need to run "su" or "mu" to get Root. Once Run as Root it'll automatically rename SU as needed.

NOTE: If it seems SU has disappeared then read this other post I made:
I believe that for some reason the renaming process using the app was interrupted or SU was placed in the wrong folder for your device by accident (ie: /system/bin instead of /system/xbin). My script can't detect that kind of problem as there is no way to and it wouldn't be possible to fix it.
The best fix would be to flash SU back to your device using CWR either with a SU update, ROM update, or NAND backup. Alternatively you could use ADB on your PC to push a copy of SU to your Android device. Please be sure you push it to the correct folder (some devices use /system/xbin instead of /system/bin)
