Are you positive that the problem is memory and not CPU? Most decoding of
audit and video is very cpu intensive. If the audio/video app gets swapped
out (of the cpu), you can notice choppiness in quality. A good graphical
tool such as Xosview can give you an indication where the bottleneck might
be since you can see CPU, memory, swap, disk, etc. all at once and see what
is pegged.
