Uninstaller.... This method is not a true appreplacement, but here it goes. Go to http://www.nirsoft.net/ and grab myuninstaller. Place the exe file in hfexpert\win\system32. Then when you want to run it, type start/run and type in myuninstaller.exe (or whatever the file is called). mediaplayerclassic. If you are using FDV's fileset, you are also removing media player. If you carefully edit FDV's files, you can use appreplacement for media player. If you don't feel like editing files, just put the renamed media player classic file into hfexpert\win\system32. To launch, start/run and type in the exe filename.
