Exuberantly Frustrating.. just throwing more PROPRIETARY Video codecs out there. NO PPC Support, Demands much CPU, Has security holes. Loaded with M$ DRM. Kinda scary some of this stuff! Quality of video is deplorable on the mac, while on the PC it's mediocre at best. The sheer fact that this video codec is as inferior as it is on the mac in comparison to its PC counterpart should upset most. Micro$oft on YOUR mac, think they have your best interest in mind?
