SMB is listed as experimental but I thought DLNA was supported in this model. It does no harm to send Support an email to ask for help.
Thanks ... and how does it connects to the Oppo wirelessly?
I use this one as it uses the rear rs232 serial and USB ports and its $15 off till June 1st. It comes as a region 0 (all regions) for DVDs and Region A for Blurays.
The link you provided for the external mod connection is for the 93/95 and not the 103/105, hence the $30 price difference between the two of them.
I have just been told by Oppo a few minutes ago that they anticipate a new FW release at the end of the month. I was asking about a fix to something unrelated to your problem. IMHO, I would wait a week or so for the new official firmware... It will have fixes to the beta and obviously other stuff as well.
