Will review it this evening. Hopefully it won't be removed from the AppStore before then.
Very poor, not recommended. Go for something better; for example, the existing (1.10) version of nPlayer is WAAAAY better in every respect (HW acceleration, subtitle / streaming / container support etc).
Just some specific thoughts:
H.264 decoder: not the fastest (unlike, say, AVPlayerHD, nPlayer etc.)
MKV decoding: software-only; this, along with the not state-of-the-art H.264 decoder, also means playback of even standard-bitrate (about 10 Mbps) videos (e.g., the Monsters one
http://www.auby.no/files/video_tests/h264_1080p_hp_4.1_10mbps_dts_unstyled_subs_monsters.mkv ) aren't played back flawlessly on not even the latest-gen, fastest devices (iPad 4, iPhone 5), let alone slower ones. On the latter, 1080 MKV playback is plain useless.
MTS / AVI decoding: software-only
Codec support:
DTS, AC3 are both properly supported
So are OGG, mp3 etc.
Subtitle support:
Nope
Container support:
ATSC 1080i60: tolerable (as opposed to DVB, at least it's 16:9), no scrubbing
DVB TS: very poor: 4:3 only, no scrub (no subs)
NOTE: retina support on both iPhones and iPads must be manually enabled!
