Answering a question HERE, I've thoroughly re-tested the current version (1.5.3) of AnyPlayerHD and found out that it's equally bad (very low-performance decoders, no hardware MKV acceleration etc. etc.) as was the one I reviewed HERE, in late May. That is: this player is still not worth bothering with as there are much-much better players - even for free (for example, iMedia Player introduced below). Stay away!
