Ken,

Can you compress a copy of the original file with Rev, and compare it to the zlib compressed copy? Does the data look totally different, or maybe just off by a few bytes / headers?

If you have a MacOS X machine (or Linux) handy, you can use gzip and gunzip as command-line equivalents of compress() and decompress() and see how those results compare as well...

I'm assuming you've tried just reading in the binary data and using
'decompress' in revolution - the docs for 'compress/decompress' say
it's based on zlib compression.

Yes, I get an error that it's "not compressed data". My understanding was
that the compress/decompress in Rev is gzip format, which is a wrapper
around zlib-compressed data. But beyond that, I have no idea...
