Help Video Playback is laggy on the computer

[PRkid]

So I recorded a couple videos on Christmas, and video playback on the phone is perfect. No lag at all. Today I connected the phone to the laptop via USB, played the video, and when the video was playing back, it was super laggy. Looked like I kept pressing play and pause throughout the entire video. Any reasons why this may be? I used WMP and Quicktime to play the video, they both lagged.

You tried a different player? Vlc maybe? What did you record in? 1080p?
