Extracting images

[s367610 at student.uq.edu.au]

Hi - I'm trying to read in a MPEG File and extract it into a whole heap 
of .bmp files.  At the moment I can get it playing onto the screen, but I 
can't seem to find anything that would allow me to get the pixels out of a 
frame.

Is it possible and if so how do I do it?

Thanks,
Dave
