The new version, which handles the new ZIX format, is now finally available for download.
ZIP version (4.79 MB)
Bittorrent file (so you can share the burden of uploading)
Sorry about dragging my feet this last week, folks. As a small token of gratitude for your patience, I went ahead and added support for 3w-encoded AVI files.
Thus, if your'e unlucky enough to encounter another ZIX archive, or another encrypted AVI file, this utility should be all you need.
