I have a major problem with my WD TV Live Plus with firmware 1.06.16_B any video I play over network share on Windows 7 will stutter , the same thing happens when playing over media share, however if I copy the same file to USB it will play perfectly.
After trying many things (replacing cables, older firmware) I found out that if I put in static IP addresses on my network share computer and on the WD and connect directly to a hub without the ADSL router (Zyxel P-660HW-D1) it plays perfectly. This leads me to believe it is either my router or the WD that is the problem.
So I tried connecting my 10 year old Xbox with XBMC and connected it in the same way to my router as WD and it plays the same file perfectly over network share.
This leads me to believe that the network code in WD TV Live Plus is just fundamentally broken.
