I am having difficulties streaming my windows xp computer to my PS3. I have enabled media sharing on both devices and allowed the PS3 on my computer. I am also able to connect my windows vista computer on both my XP and my PS3. To make things more interesting, up until two days ago the PS3 was able to connect to both computers. I have tried cycling the modem and the router to no avail. Any help would be greatly appreciated. p.s. if this should be posted in another part of the forum, I do apologize and will move it if necessary.
