I’m working hard on getting VLC Streamer ready for iOS7.
I am aware of one major issue; When movies have been copied over to the device, they no longer play (or at least – they are very distorted).
I have just figured out a workaround (Thu 19th) so I should have an update submitted to the store shortly.
In the meantime, streaming from your Mac/PC should work correctly.
I’m sorry for the delay, and hope to have an update shortly.
