Thanks for link Andrew, very interesting stuff. But I guess you had very well covered the compression part. Couldn’t find anything more. :-)

Jim, I think zippy is the name they have given to their internal modified version of LZW.

I’ve combed google and usenet for a while and still can’t find any direct references to the “zippy” algorithm — any pointers?

You have to watch the video. They just posted the high resolution video. WMP on the Mac really sucks, but I managed to find the location where the compression talk begins. Jump ahead to 46:30 if you just want to hear about compression.
