Bonjour drop out on Eye TV

I had lost access to Eye TV which appeared as a problem with bonjour and after alot of fiddling around the problem seem to exist when the iMac was using the Time Capsule for the wireless access rather than the AirPort Express. Both these devices where set up as the same network. I have now split them to 2 seperately named access points. I access my Eye TV via the Netstream DTT tuner (x2) located on the local network.
