Better than WD TV Live Plus?

I own a WD TV Live and want to purchase a box that will stream NetFlix while still allowing me to access my multimedia on my home media server.  Can anyone tell me if  the WD TV Live Plus direct competitors are better?  I’m looking at  the Seagate FreeAgent GoFlex TV and Roku XDS.  Both devices seem to be very competant at streaming online media, but they don’t seem capable of accessing media from a home server.  Is this the case?
