I have an lg g3 ,the phone its recording videos in fhd at 60 fps,the problem is the videos are not very smooth are choppy,its not a problem with hardware because the videos are very smooth in mint17 cinnamon but in kde are choppy,and its not a mint problem because i have try kde with other distribution and the same problem ocurres,i like more kde and from two days i have try to get a sollution but without succes,what its the diference in cinamon and kde at videos playback or what i can do to proper video pl;ayback in mint 17 kde or other distribution,i have a amd athlon2 x3 cores at 3,3ghz,8gb ram ddr,ati radeon HD 4670 512mb

Can you please clarify the problem? Have you tried multiple players - as it could be a backend related problem?
