I have the same problem.
3 PCs:- 2 on Win7 and 1 on XP
WDTV Live Firmware 1.02.21 / 1.03.38_V
WRT610N v2 Firmware 2.00.00 B05
All of the above are in the workgroup, WORKGROUP
All 3 PCs have access and can see each others Network Shares in windows and can also see WDTV Live in Networks.
However, from the WDTV Live, only the XP shares are visible. Win7 shares from both PCs never get detected no matter what.
After reading this thread, I checked which PC had MASTER BROWSER status. After a few hours of testing and rebooting, I conclude that my WRT610N always gets MASTER BROWSER status.
SOLUTION:-
Changed WRT610Ns storage workgroup to HOME. (storage-administration tab)
VOILA. 1 of my Win7 PC got MASTER BROWSER status and the WDTV Live can now see all Network Shares from all PCs.
