Hi, I can't promise the will work but assuming that the files are Silverlight and are not DRM protected (and you run Windows) you can try the following.
You will need for this:
ismdownloader and ismdownloader AVC1. You can get them via the two links in red at the top of this page:
http://md5decrypt.altervista.org/ismdownloaderavc1.htm
Unzip those files into their own folders on your desktop.
Install the Firefox extension called HttpFox (you can search for it in Firefox by going to tools>>Add-ons>> extensions and putting HttpFox in the search bar).
Once that is installed, open the ismdownloader folder on your desktop and open a command (CMD) window 'inside' that folder. To do this, find a blank area in the folder, hold down the shift key on your keyboard while you right-click with your mouse. You should see an option to "open command window here" - click that.
Now a little preparation...
1) Open a new text document
2) Grab the full path (address) of that ismdownloader folder and copy that in to your text document. To get the full path you can click in the blank space in the folder's address bar to the right of where it says ISMdownloader so the address changes to read something like:
Code:
C:\Users\IEUser\Desktop\ISMdownloader
Yours will be different to mine, obviously.
3) Paste that path in to your text file and add double quotes around it. Then add: ismdownloader " /Manifest" to the start of the line and at the end of the line add myvideo.mkv. You should end up with something like:
Code:
ismdownloader " /Manifest" "C:\Users\IEUser\Desktop\ismdownloader myvideo.mkv"
The info you get from the next step will be pasted after the double quotes that come after the word ismdownloader.
4)open HttpFox (it's under 'tools>> web developer) and in its search box type .ism - now click the HttpFox start button.
5) Visit your website and play your video. With any luck you will get just the one result in HttpFox. You might need to edit what you get so that it ends in .ism - Copy the address it gives so it goes before manifest in your text file. It should look like:
Code:
ismdownloader "http://The-Address-You-Found.ism/Manifest" "C:\Users\IEUser\Desktop\ismdownloader Video.mkv"
Copy that complete line and paste it in to the command (CMD) window you opened earlier. (On the top left of that CMD window is a tiny black box - click that and select 'edit' then 'paste' - Press 'Enter' (return)
If the gods are with you it will work. If not then repeat these steps but using the folder ismdownloader AVC1 - grab its full path and open a CMD window there etc.
