I really hope that someone can help. I've used MB3 since about January and had no issues until a month or two ago. I use MB3 primarily to watch my movies (mp4/m4v) on the iPads via the media browser app (latest update). Previously, I had no issues watching movies both within my network and externally. Then, all of the sudden, playback stopped working on most movies and I can't figure out the cause. I have an iPad 2 (iOS7) and an iPad Mini (iOS8) and both have same issues. I am able to see the library and select the movie, but the movies just won't load. Just get the spinning wheel and sometimes I have to manually kill the app to get out of it. It doesn't happen with all movies, but it happens with most. To clarify, if a particular movie doesn't work, it never works and if a movie works, then it always works. Server (Version 3.0.5395.0) is on a Windows 7 64bit machine. If I use Safari to access the server, I am able to play all the movies fine. I am okay with doing this but that process is not so easy for the other people in the house.
I've uninstalled the app and MB3 Server and started from scratch but had no luck.
I love this program when it works and I really hope that someone can help me with this.
Attached is the log that I think that you need. I looked at the transcoding logs (I enabled them) but it doesn't create a log when movies fail on the iPad; it doesn't get that far.
