We are working to address cache issue right now.
I have only ICQ or Skype and we are in a GMT+2 timezone.
As for load delays, I need to see the effect. There is nothing in HotlinkBlocker itself that can delay.

Please download and upgrade to the new HotlinkBlocker 1.4 This new version should address your issue with a client caching. Please set a link expiration value to some significant amount, like 3600 sec. The links on pages will be regenerated in 1/2 of this period.

just tested a bit more.

The first time load is a bit faster than before.
Before it was 1,2,3,4,5% now its like 9,18,25,45% it's still not as good as if the protection was not on but its way better than before !

During heavy load it seems that it has a bit hard time to cache video files.

This is an illusion, or I am missing something. HotlinkBlocker does not do anything on a responses other than text/html content type so it cannot hamper media file load, if the load process was started. Can you please show me example of such delays?

I understand that under different load response time may vary, but I don't see how HotlinkBlocker itself can affect this performance.
I have checked your live link and now I have more information. First of all why you are using http://64.72.125.88/video.asp?media=... page wrapper around the video file? File video.asp is not protected itself against hotlinking, so it will be still possible to hotlink using this format. You need to embed files directly into the page in order for hotlink protection to wrok.
Also your content is spread on a number of different hosts. Cross server and cross host hotlink protection was always not as simple task.
If you embed media directly to the page you will need to install HotlinkBlocker on both servers to use LINK protection. One will be signing links and second will check signatures. You will need to copy Signature value from one HotlinkBlocker installation to another.
Or even better utilize REDIRECT protection instead of LINK protection and whitelist referrers.
Anyway I suggest you to try redirect protection on some test links, it should work better in your environment.
Also tomorrow we will release upgrade build that will work better for client caching.
