At this point (w/o doing the actual troubleshooting session) I'd say that you just collapse your networks into one flat 192.168.1.x (you don't need multiple networks anyway-not like you're firewalling and enforcing security policies b/w them anyway, are you?)
I do need them, because I have employees, friends and family using my WAP that I don't want to even see my LAN. The TV and the BRD I can solve most of the problem just by plugging the media devices switch into the WAN, because they don't need to access my LAN, but the WD live does.
For the time being I have done this, although I am going to try and forward the TV devices IP number to the WAN as a gateway and see what happens.
