BT Youview channels not working since Ive installed ASA 5505

I have recently installed an ASA5505 as a domestic firewall.

The ASA5505 is sitting behind a Netgear DM200 Modem Router.

The setup is as follows:

ADSL Line <-> DM200 (public IP is dynamic)

DM200 (private IP is <-> ASA5505 Outside Interface ( The network is a /30 subnet.

ASA5505 BT Youview interface ( eth 0/4 <-> BT Youview box

This is a double NAT setup so Ive struggled slightly...

I have been unable to get any of the BT Channels since I installed the ASA.

I have placed the running config below for assistance:
