[#io.quicktimeapple] is an object class written specifically for Apple's 
QuickTime. We just don't have that much experience and that much time for 
programming for OSX.

[#io.quicktimehw] is an object class written for another component called 
"libquicktime", usually found on Linux, but that can be made to work on 
Linux. Its code has nothing in common with Apple's QuickTime, except for 
the file format it supports in the end. This is the component we use

I would like to know about this problem, because if you're really running 
GridFlow 9.9, that version is supposed to be the one that we fully tested 
for bugs about "bluish hue". In the meantime you can use [#inner] or 
[pix_colormatrix] to swap channels :

   [#inner (4 4 #   0 0 1 0   0 1 0 0   1 0 0 0   0 0 0 1)]

But really, I would like to fix that bug (and [#inner] isn't so fast). 
What you are using is [#to_pix] and not [#from_pix] (the latter converts 
Gem pixes to GF grids instead). Open the help for [#to_pix] and look at 
the numbers you see. On Linux, the [pix_info] number is 6408. On 
OSX-Intel, there is a different number, and on OSX-PPC, it's yet another 
number. Check the box that says "this is supposed to have no effect", to 
see whether it makes any difference on the second [pix_info]. I would like 
to know the numbers that you get, because it could be a big hint about the 

Patrick, did you retry on a real PPC box after 9.9, or did you only use 
the PPC emulator ?
