OSStatus error - 19160

[Matans844]

I'm using a Mac computer and I have trouble viewing Windows Media Video
from a specific streaming website.
I have the latest versions of quicktime player, flip4mac, VLC and the latest operating system.

The website I'm trying to view videos from is a private server, which
requires VPN connection. This means there's a password and a username needed. This password changes every couple of minutes. I cannot download the videos. I can only watch them.
After successfully connecting to the network I was not able to play the videos.

At the beginning I received the following message:

OSStatus error - 19160

Searching for solutions online I ended up at the following thread:

I installed VLC but still the videos did not play. I received the same
error message.
I installed Perain but still the videos did not play. Now I don't even get
the error message.

Any help will be appreciated.
And if you need more information just let me know.
