I rip my Blu-rays. They are expensive, and scratch easily, so I'd rather not play the actual disks when I can avoid it. As such, this software is useless to me because playback of ISO and directory rips is choppy well over half the time (as it turns out after 2 days of tests, even though the rips in question play just fine on my Windows system). As importantly, I don't even get to experience choppy if I decide to play them in full menu mode. 8 times out of 10, the player just crashes or freezes.
I should have experimented a hell of a lot more before shelling out $30 because this purchase was far from worth it, even at 50% off. ($60 is too expensive even if the software worked as advertised, which it does not - the ISO and directory playback of Blu-ray rips is it's listed as a feature in that glowing description, when in reality, it's still just a bug.)
Avoid, unless you don't mind using this as an overpriced alternative to VLC that looks better, but works worse.
