The default IP for the Linksys WRT54GS router is 192.168.1.1. Just enter this IP into your browser (internet explorer) address bar from your connected PC and it should take you to the router login page. If you never changed the default username and password, just leave username blank and enter 'admin' in the password box. Select 'Applications and Gaming' at the top of the Setup screen, then select 'Port Range Forward' from the menu. You should now see the port forwarding screen where you setup your DVR. Port 3389 is the default port used by Windows Remote Desktop Connection. Enter 3389 in the 'Start' and 'End' boxes and your PC ip address in the 'IP Address' box. That should do it. Be sure and assign static IP addresses for your PC and DVR while you are in teh setup menu, to avoid possible problems.
