Well if you do leave both firewalls on then you have created your own DMZ type setup in the 192.168.0.0/24 network and you internal network on 192.168.1.0/24.

In theory there should be no problem with internal network stuff seeing both the DMZ where you have your BluRay and other AV kit and the outside world. Stuff in the DMZ shouldn't see the internal network unless you want them to. You could use the wireless on the SH as a sort of guest network where it can see the wide world and your AV network but not your internal equipment.

Where the "fun" would begin is if you wanted to open a service on the internal network to the outside world as you would need to chain the ports but it should still work.
