Subsequent testing last night shows that the program can play movies and video files okay but cannot play BDMV folder structures. That is okay for now since in time I suspect he will provide it also.
Interesting that you cannot see the DLNA servers. Since it is working on my system it means the software does work, but there is a difference in configuration. I am using the Generic configuration, with the defaults. When I select networks at the bottom of the screen (IPad nPlayer program) then it immediately displays the JRiver icon. First time it did not do it but then I realized I had forgotten to run the JRiver program. As soon as the MC started on the PC the IPad display updated and showed the MC icon.
Let me know if you still did not get it to work and I'll see if we can compare configurations to find the difference.
For watching DVD's (IFO file structure), videos and music it is great. A few quirks, but looking at this change history it appears he is very actively involved in updating the software, would be great to see him team up with the JRiver guys to develop a IPad program with the same outstanding quality and function of MC.
