Apple user: Mac shares problem?

Yup I read most of those but they don’t exactly match my problem (I think?).  I don’t stream from my Mac or use my Mac as a media source.  In fact I don’t use anything for my media streaming except the WDTV Live SMP’s. I was hoping somebody had my specific setup and could tell me how to make the SMP’s work with each other over a wireless network. 

It is possible that I could have missed a thread though.  I will review them again.  If you know of a thread that solves the problem of getting 2 - 3 SMP’s to work together over a wireless network using MAC shares, with one of the SMP’s having an attached HDD (containing the video media) please let me know. It sounds easy but I haven’t been able to solve it Thanks!
