media center, wireless network, 360

[deathwarder]

ok, I have a really weird setup that i need help with, I have 3 media center pcs, an xbox 360, a wireless connector, and two routers, both wireless

My main mce comp is where I store files, plain and simple, it streams to the others, and to my other comps which I use as extenders, one of the mce comps has a wintv card in it, it is the pci 878 model, if you google wintv, click support, click pci boards, and click 878 model or something like that you will find it, that mce comp is attached to a wireless router, which is attached to my wireless g network, my server, cable modem, and non-mce comp, then the third mce comp is connected to my 360, and uses the 360 as an extender, so here is the problem, the tv tuner comp keeps saying there is no tuner when in tv settings, the third mce comp is needed elsewhere by my parents, they dont like the noise, so can I hook up my wireless b router to the 360 as a connector, and not as a wireless extender? If so how? Finally, how do I stream live tv from my tuner to other comps? Sorry if this is asking a lot

also, I forgot this one, the tv card in the mce comp doesnt seem to give me sound, and doesnt work with mce for some reason, any suggestions?
