The problem is that when the the movie is copied to the hard disk, it is given a filename based on the URL of the imagemap, not the URL of the of the actual file stored in the imagemap configuration file. Thus, the movie filename no longer ends in .MOV; it ends in .CON (from the extension I use for imagemap configuration files, .CONF). This by itself should not be a big problem, but Media Player identifies the type of file it is about to read from the extension. If it was a nicer application, it would look at the head of the file for information, but it doesn't do that, so what can you do?
If you want to still use Media Player, view the clips from the Press Room instead--there are no imagemaps in the way to confuse the issue.
However, I recommend you install the real QuickTime for Windows above and change the .INI file for your Web client to use Apple's Movie Player.
pkunzip -d qtw111.zip
This will make two directories called DISK1 and DISK2.
cd DISK1
xcopy *.* a: /s /e
label a: DISK1
XCOPY the contents of DISK2 to a blank, high-density floppy labeled as DISK2. Copying the files to floppies is important; QuickTime for Windows SETUP will only install from floppy disk.
