Now… it has the same file association preferences as the MacGo Blu-ray Player (I can't understand it, it takes everything over and gets quite a bit on my nerves). The app is also localized in a number of languages, which is a plus on my book!
The only thing I didn't try was Blu-ray disks (but the file association preference seem to imply it might read them - which I find storage since the same company sells a blu-ray player and this app is free). It played mostly everything I tried and didn't have a crazy footprint on RAM or CPU. I'm not sure what's going on wight he extremely positive and negative comments but I tried to give it a fair try.
Not a bad player, not the most amazing and comprehensive player either.
