why are you using two routers, all you need is one router like a netgear,tompson speed or a zoom and a pc running windows xp media center or windows vitsa.
if you are using media center than you will have to download the 360 connect which you can get form xbox.com.
if you are using vista windows media player will handle it .but which ever opsystem you are using you will have to set up a conection on the 360 .
so go into media center on the 360 (click on the windows logo) then select setup conection and follow the on screen prom's write down the the key number on the screen then again follow the onscreen prom's(360 screen that is) now if xp media center run the software downloaded from xbox.com and enter the key number when asked for (tip shut off any firewalls that are running).
if you are using vista switch on your 360 and fire up media player and select liberry then select media sharing then you will see a box come up with a icon reping your 360 click n properties and you can enter the key there and setup which folder you want to share
