Hei Menneisyys2,
I noticed CineXPlayer has updated its app a few days ago with a new UI and music playback support with Dolby Digital Plus, as well as Live TV. I'm sure you have tried it and talked about it before, it seems the app is solid with MKV and AC3 support on the iPad version (iPhone version doesn't support MKV for some reason).
So you think it's worth 3,59? They had me at new UI and music playback, as I'm looking for a single app to handle all multimedia needs. Too bad it isn't Universal and lacks parity with the iPhone version.

Basically, I don't recommend it over nPlayer or AVPlayerHD. Only check it out if you can / want to make use of its Dolby Digital features, built-in Web browser or TV station directory. As a standalone video player, it's considerably weaker than nPlayer or AVPlayerHD.
