I had the same results when I tried modifying the color of the "M" logo to orange instead of red. Don't know why, but nothing...Just a blank screen where the ani should be.
I was, however, able to edit out the "Dual Core" part using Gimp and just painting over that part in black. I'll attach the new animation. Doesn't seem to run as smooth as the original so I won't be offended if you don't use it and think it's crap. I'm ok with it and I'm using it as is.
Note: Don't forget to rename to bootanimation.zip before applying and ( disclaimer here: ) I am not resposible for what happens to your phone. Use this at your own risk. Etc...Etc
