Just as an info for those, who might have problems with Samba shares with their Oppo's...
I got problems with SMB last week and initially, I thought the Oppo is broken, because he behaves very strange and at last he didn't want to play files even from USB.
So I sent him to service, but they didn't found anything strange. I got him back today and unfortunatley the same thing... no SMB shares to view or to browse.
After some checking the network protocols, I was curious, that he didn't even looked at the SMB shares provided by my NAS.
The crucial hint was then to isolate both in an extra VLAN ... and guess what happens... everything was ok again.
Finally I found out, that a printer, which I installed last week in our network was providing his own Samba server and somehow disturbing others. At least the Oppo has been knocked out by him... ah, yes, it was a Canon MP640 (universal printer, copy, fax)
