Things you don't want to start up automatically should first be disabled in the option of the program itself, or these may override the Msconfig settings, as you have noticed.
In case of Real Player: View/Preferences/Start Center/Settings/remove check mark.
If you want to get rid of the unchecked items in Msconfig that you'll be sure you'll never need, you'll have to edit the registry:
Start/Run/'regedit'.
Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run- and RunServices-
Note the - (minus) sign behind Run and RunServices.
In those two subkeys you'll find the Msconfig/startup entries that are UNchecked.
Highlight the ones you'd like to get rid of in the RIGHT pane, and choose 'delete'.
And next thing you know, they're gone...
As I said, don't remove stuff this way you still have, and might want back in startup, for in that case restoring them gets a little more complicated.
Good luck,
