Summary: plat-mac/videoreader.py not working on OS X

Initial Comment:
plat-mac/videoreader.py uses modules like "img" which 
used to be in Mac OS 9 builds, but are no longer in OS X 
builds. I suggest replacing the pieces with code writing 
images using PIL, if available.

The critical new pieces (whithout checks for PIL) in methods 
ReadVideo/_getpixmapcontent are:

#-----------------------------
from PIL import Image
...
# convert from ARGB to RGBA (faster/better anyone?)
data = []
for i in xrange(0, width*height*4, 4):
        a, r, g, b = rv[i:i+4]
        data.append(r + g + b + a)
data = ''.join(data)
# save image using PIL
img = Image.fromstring("RGBA", (width, height), data)
img.save(<<some filename>>+".jpg", "JPEG")
#-----------------------------

script:

February/010282.html

or see the attached file (which does not do exactly the same 
as videoreader.py!)...

PS: This is on Py 2.3.3 on Mac OS X 10.2.8...
