after recommending wdtv to all my friends, I finally managed to get one for myself!
i have a wdtv live smp which connects to my readynas duo via smb, over wireless.
it usually works just fine, but on occasion i will wake it up, and upon opening a media category i get a message telling me the current media source has been removed. When i reconnect to the share, it tells me that there is n media in the current folder. I can still access files fine on other devices.
the only way to fix this seems to be to restart the wdtv, or wait a long time and eventually it works again. I can also try to use the media server method via readydlna but it is generally slow and not as well organised as browsing samba as i like my tv shows and movies divided :)
If I change my media source to something else (such as the same NAS but as a media server instead of network share) before I put the device to sleep, I can always connect back to the network share when waking it up without a problem.
Therefore the problem seems to lie in either sleeping, being asleep, or waking up while the media source is set to the SMB/Windows share.
