I use zoneminder 1.24.4. In a logfile /var/log/httpd/access_log in an error when opening ZM4MS playback
192.168.XX.XX - - [08/Sep/2011:13:22:57 +0400] "GET /zm/events/19/187321/007-capture.jpg HTTP/1.1" 404 311 "-" "-"
but the event looks like /zm/events/19/11/09/08/13/25/57/007-capture.jpg
On the site of ZM4MS (jpwilson.eu) write, what All support for ZM4MS is via the zoneminder forums.
