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.
