If you can spare that amount of RAM then grab YUV42? frames.
More knowledgeable people, please correct me if I'm wrong, but
I understand that YUV420 for example takes WIDTH * HEIGHT * 1.5
bytes of memory; one PAL frame would be 768 * 576 * 1.5 = 663552 bytes.
So if you have 192 megs of memory you will get:
201326592 / 663552 = about 300 frames.
