I just checked my machine and I was able to use the scroll bar
on an Archived feed. Check to make sure you have all your updates on your PC. Including IE8

Try uninstalling the ActiveX control and reinstalling.
To uninstall, navigate to Control Panel > Programs and Features and uninstall the Cisco Video Surveillance Client. Reboot your PC.
When signing back into VSOM 6.3.1, you will be prompted to install the ActiveX control again. Alternately you can (before uninstalling) navigate to the VSOM Admin page, Utilities >? Software & Downloads to download the VSOM Video Client manually so that you may reinstall after the reboot locally rather than relying on VSOM to ask permission to install the client.
