I downloaded the light program only let me play only for 2 min, the 2 min it let me play was amazing!!!!! So i bought it, i should have no bought it did a little more research if you have a 1080p movie on you mac and streaming it freeze every 5 to 10 min. I have very good internet 50mbps down 5mbps up, and i am not downloading or uploading anything. im sure lower rez movies will work better if not flawless. would be great if they can fix this issue, or put out a how to fix lag issues.
