How to change the port for a virtualhost ?

[Spheerys]

Hi,

I try to use an opensource solution to host video on my web server.
This solution is http://mediacore.com/
It's a python program and the installation is not easy, but it's look good

I try to install it on a subdomain : http://video.domain.tld

But on my server, ispCP is runing with an Apache instance.

So MediaCore don't want to run on the port 80 because is allready in use.

How can I modify ispCP to run the virtualhost http://video.domain.tld managed by ispCP on another port (so the port 80 will be free for mediacore) ?
