i agree with that one, but i do think that any further compression will come at the cost of processing time, and since hard drives now can hold 1TB and are cheap, processing time is viewed as more valuable. So we are possibly going against the grain of what most compression does (something fast). However, i will again add that MAYBE this isn't entirely true either, i'm still interested in what your method is. Unfortunately i still have issues understanding while reading what you've posted thus far on the issue.
