I click “Simulcast” and nothing happens

This is caused by a pop-up blocker. The blockers come in many different forms and if the user has Windows XP Service Pack 2 then there is a pop-up blocker built into Internet Explorer. Please note some pop-up blockers need to be removed and some can simply be disabled. If you disable the blockers but they still block pop-ups you need to remove it completely.


Hint: Most of the time many of these pop-up blockers can be bypassed by holding down the “CTRL” key and clicking “Simulcast” at the same time. This can be used with the following products:

  • Google Toolbar
  • Yahoo Toolbar
  • MSN Toolbar
  • Sensis Toolbar
  • Norton Internet Security

I launch Simulcast and it says “Error Creating Socket”

The socket connection error will cause the user to not receive audio and video streams and in most cases the user will not be able to successfully establish a connection to Simulcast. To resolve this, ports must be opened on your proxies and firewalls to ensure a connection can be made to Simulcast. A list of the ports can be found below.

Network Details

Some larger networks may require certain ports to be opened in order to run Simulcast. The details for this are listed below.

When I click on “Simulcast” the window opens and I receive a red cross in the top left hand corner

This is caused by the computer/network security policy being too high. To resolve this, the security must be lowered to medium-low and the cookies and temporary files must be cleared.

I have Simulcast open, however I can't hear any audio

Check to ensure the audio plug-in has been installed. If this plug-in has not been installed you may need to lower your internet explorer security settings in order to be prompted to use this audio control.

I can hear the auction but I can't see it

This is caused by low bandwidth. Simulcast can adapt as bandwidth runs out and in order to keep bidding integrity it will drop frames per second and sometimes video to ensure audio is crisp and bidding is instant.
