'play to' not working on windows 7 'wd tv live hub'

[oli_ferns]

I have a wd tv live hub and I have 2 windows 7 x64 sp1 laptops. The 'play to' feature on works on laptop A but does not on laptop B. The 'play to' feature actually enables you to play your music/ movies on your big screen via the wd live hub from the laptop. 

On the non working laptop, it shows the busy circle and gives up after a minute without any error message.Check the screenshot-

The working laptop is a clean install with no third party programs installed.

-I've tried the following on the non working laptop-

disabling the firewall and auto-protect feature of Norton Internet security 2012

-Creating a new user profile

Both of the above haven't worked. My next steps would probably be a clean boot or a complete uninstall of Norton.

Just wanted to know if anyone has been through this before and if you've managed to get around the problem.

Update-

A complete uninstall of Norton or a clean boot has not worked.

Wondering if vlc player could be a problem here

Thanks

Can you access the problematic computer as a shared resource from the hub?

There are some settings that might need to be tweaked but not that familiar with "play to"

I just access the files as a media server or shared folders on my computer
