Network shares not showing up

Hey man, had the same problem as you w/ the WDTV Live and the Linksys e2000.  I am about to try your fix now.  Just changed my workgroup for my desktop to WORKGROUP-NEW and now im going to do same on WDTV.  I guess the router will always default to WORKGROUP?   Any reason i wouldn’t want to do this? ie having my router on a different workgroup than my pc?
