Replying to Help with editing?

Hey M&A, okay so I'm not a "filmer" I have a gopro and I finally got around to using it, so today I brought it skiing and got some shots with it, and I am an IDIOT when it comes to film/editing, so I put the clips in an editing software, (FIRST it was vegas) and it was really choppy, like playing in frames and skipping like 5 seconds at a time, then I tried a bunch of different editing softwares. (Camtasia, AVS, GoPro Cineform, WLMM) and they were all choppy and in frames. Could someone please give me a hand with this?
