I'm impressed with VLC for iOS 2.6.4 - it can connect and play .ts from my HDRs by DLNA or FTP, and has a good stab at HiDef playback (sound is fine, video extremely stuttery probably because my ancient iPad isn't pokey enough).
There is a problem: weirdly, disconnecting VLC from any of my HDRs causes a networked HD-FOX to reboot!
I think it ought to connect with the default parameters, but you're right - I can't get anything either. Maybe it needs fixing; here's something I found on their release notes:
For iOS and the tvOS application, we've submitted all the applications. We're now waiting for the Apple Store reviews.
It might be long to review, because of the holiday season!
And of course, we've already fixed a few bugs on the master branch, but no major feature, until we get a release
I am using the version of 29th. DLNA works fine for me.
I get list of files. When I select one to play it appears at bottom of list in a small picture (it isn't obvious unless you look), I then have to hit full screen icon on right.
