Good you sorted it out.
I've found the VLC app (2.4.1) annoyingly temperamental on my iPhone 5S when trying to play from my Fox T2 and Foxsat (with the custom firmware). If you run into any snags, try MoliPlayer; I was sceptical, having tried plenty of other players, but this one really does deserve the 5-star reviews that the vast majority of the 58 reviewers have given it - it's the only player I've found that consistently plays all the files I have on both machines. I only came across it by accident because of frustration with VLC. (I unblocked all 8 plugins for a small price; included in which are: download via samba, download via dnla/UPnP, but I found the free version perfectly good).
