I have some problems with some mkv (can’t find what links them) that I play with infuse on an iPad Air with an iXpand usb3.0 key.
Sometimes the videos freezes and after that the audio is no more synchro with de video. Sometimes the video jumps by itself forward.
I try it with an iPad pro and an iPhon7 also, and it also happens.
The firmware of the key is up to date, and even more weard, sometimes when I try again a file that hasn’t worked earlier, works fine …
Any idea ?
