Uninstall software in custom rom

[Millz-Mal91]

Ok at this point Im tired of reflashing so ill ask.....is there anyway for me to uninstall a software that I cooked in with the 6.1 rom? its pretty much the youtube player, i t keeps saying it can't retrieve the youtube cookie and when I went to install the external cab for the software it works fine, however now I have two youtube player icons in my program list, one for the prebuilt and one for the external. how do i get rid of the prebuilt one
