I spent several hours to find the reason when and why this Problem happens, but i didn’t find the reason.
My conclusion is:
-
The workgroup has nothing to do with this problem. Even if WDTVLive is the only device in “workgroup” and all other PCs are in another workgroup, this problem appears.
-
Even if the WDTV is in another workgroup the workgroup of the PCs is cleared
-
I didn’t find a trigger for this beheavior
-
The DDE Services can’t be the solution because they are not implemented after XP
-
It doesn’t matter if the sharing of the WDTVLive is activated or not.
My investigations with browstat.exe showed a very stange behavior of the browselist:
In all cases my Notebook (WinXP SP3) or the Netbook(WinXP SP3) has been the master browser of the workgroup and never the WDTVLive, (because of the higher OSLevel). So far so good.
After different time periods the PC from which the movie was played, disappeared from the Workgroup and the WDTV displayed the error message. Then all other PCs disappeared from the workgroup.
The really strange thing is, that even the masterbrowser self disappears from the list and then the browselist is empty.
browstat.exe says, that there is a Master browser (my notebook) an 0 servers.
The only thing that now helps is to disable and then enable the networkinterfaces of the Notebooks and the game begins again.
I tried the firmware from b-rad to see what happens on the WDTVLive and found out, that the networkshares are mounted over the IP and are still available even if the device says that it can’t connect to the network share.
It seams that it only believes to the browselist and not to the mounted shares.
But i wasn’t able to find out how the mechanism works, but it’s not my task to find this out because WD know how this things work.
Final words:
Nowerdays every network device, that use windows shares is plug&play and works in a windows network and so should it it be with the WDTVLive.
So WD is aked to solve the problem very quick.
I bought the WDTVLive because of the networking ability to play media from a NAS.
If SMB is the only way to connect to shares and that is not reliable the device is useless.
(Mediaservers are no alternative because of the limitations[i.e. VOBs])
Waiting for a corrected firmware …
