My H-23 HD DVR (and Xbox 360) is hard wired to my Linksys WRTP54G router. I have two computers running WPM 11. One computer is hard wired to the router and the other has a wireless connection. Having spent several hours, and as many different forums, I am now able to Share Media to the H-23 HD DVR (and XBox 360) from my computer that is hard wired. The computer with the wireless connection does not see the H-23 HD DVR (and XBox 360). What am I doing wrong?
