Yeah, I'd ask someone like Adywan or Darth Editous for some pointers about the PAL to NTSC dealio.

Nice clip. Reminds me to ask about another possible sound replacement issue: are you planning to do anything about the creatures in the arena? I pretty much fast forward that whole scene every time because I loathe the way those things sound, especially that big green thing. Someone experimented with it before, giving it a normal growl/roar, but I forget who... It was like music to my ears! ;)
