Pink flash and muti head output

I have two questions about the xmga driver output,

First question :

Im sorry, the first question may have already been asked but i havent found 
any answer to solve my problem. I have a g200 quad MMS on linux gentoo, im 
trying to watch a movie on the second head but i only get a pink window while 
whatching the same video on the first screen works perfectly, Is it 
normal..., may i do something against it?

Second question : 

using xmga, i always get a pink very litle flash before or after showing a 
movie, i dlike to take it off. what should i do, is it possible. i had the 
same blue colorkey in xv and  i wasnt able to take it off.
Ready to go inside the code i just want to know if it is physiqualy possible. 
I dont know axactly the meaning of this pink window, i know the movie is only 
displayed on this color but would it be possible to change that color to an 
other and how could i do that.
On other way to take this pink flash off would be to show the movie a bit 
later even if i loose a some of my movie, can any one tell me if it is 
possible.
