Bridged network and streaming media issue

[Mr Incredible]

Running Windows 7 64 Bit Host, and Window Home Sever Guest (problem also exists running an XP guest). The WHS is running Comodo firewall and antivirus.

To test this is a bridged network issue (may be security settings I don't know), I also have a USB to LAN adapter (Toshiba Multimedia Center) which I can use to connect to the network and the internet.

I use Pinnacle ShowCenter to stream media to my remote Media box attached to my TV in the lounge.

When using the Toshiba connection to the network only, my Showcenter box shows 3 types of connection to my "media server" running in the VM:
<name of the PC> which is listening to port 8000 HTTP for connections
a direct UPnP connection
Media Center connection (MS MCE)

All three connections work and connect to the server fine.

When I use the bridged adapter (network and internet work fine in the VM), the Media box only sees the first entry as above, and even then it fails to connect properly: I get something that I would describe as a webserver page error when its not available. As this connection works via the Toshiba USB to LAN Ethernet connection, I know the server is set up correctly. Disabling the firewall completely doesn't make any difference.

So, are there any tweaks that I should be aware of to allow transparency through the bridged adapter to allow streaming of media?

IP addresses, mask, gateway, dns values???

What exactly causes this is not clear, the bridge should function as normal, I have a media device(nmt) that uses shares on a vm as well and it streams even HD content fine, it might be the lan drivers in the VM, see if you have the latest intel ones or maybe even an older release. Sometimes adapter properties need to be tweaked. Do you access it via a 'name' or via IP address?

The ShowCenter listens for port 8000 and grabs the IP address of the sender and then it can be accessed.

I don't understand the missing entries under the non-usb Lan connection. I have all the latest drivers. Strange.
