sorry not sure about the sorting issues... as for the speed of the cam. I dont think theres a way to speed the cam up other then holding down the shift key.
You might want to take a look around and see if theres not a cam script somewhere available if its still too slow. If i had 3dgs installed id try to script one... however not at home... Acctually writing this from the great white north... well ok it isnt really all that white right now
