Don't know where else to put this, so....

I'm running a powerline internet though my homes electrical lines to my network media player. I don't have a problem getting internet to my Sat STB or my network STB, but I don't know how to configure my Network STB to get to my computer to play files.

Basically, I'm running internet from one router through a second router to my network media player. Any suggestions on how to configure the system so I can get to my computer?

Thanx, JJ
