Video playback problem on "Castles" program

[BJG]

We have an ancient HTML-based multimedia package about Castles by "Avant Garde Multimedia"...can't find it in Google and I doubt if they're still trading. This thing was installed long ago in a shared Windows 2003 server folder. It includes videos, but these don't show; just a little "graphic not available" indicator. (If you look at its properties, Protocol/Type/Address etc all say "Not Available".)

The program works OK if it's copied to the local drive, and I'm told it used to work on this networked drive, though I can't be 100% sure. The server has since been demoted to "member server" status in a Windows 2008 server domain, and the browsers upgraded.

The line in the webpage which is supposed to show the video is:

<img border="2" dynsrc="@@/films/NDevelop1.wmv" start="fileopen"></p>

(The "@" symbols are "."s...I've had to replace them because the forum code messes them up otherwise.)

I've tried IE and Chrome, and running the thing from a subfolder in the Intranet, but it makes no difference. Since it runs OK from the local drive I'm wondering if it's some kind of browser security setting. Any ideas...?

Are the WMVs there? ../ means one folder 'up' from the referencing page. Can you try replacing them with absolute links (eg file://server/share/films/ndevelop1.wmv)?
