Adobe Premiere Pro CS6 and Canon 5D Mark 3 issue - footage is very choppy

I just got a clean, updated install of APP CS6 and took some video with my new 5D Mark III, but it seems that neither Quicktime or Premiere Pro CS6 likes the footage. It's really choppy (although the audio seems fine) and will only play about a 1-2 seconds of clean video before it stutters to the point where the video basically freezes.

I've scoured forums looking for a similar issue and found people having issues with an older version of Premiere and the older Mark II. I followed their advice (tried renaming the files from .mov to.mpg with no luck). I loaded the footage into I-Movie and there are no issues, so I know it's not my machine (a loaded, current model imac with 16 gig of memory).

I'm logged in by default as the administrator, so I think I have the correct permissions set.

Is anyone else running into this problem and have a workable solution?

First off, thank you for the response and link to your site. I followed the video, added my video card to the Open CS supported cards text file,etc... but when I open CS6, I don't get an option to select anything other than "Mercury Playback Engine software only" (which is greyed out and not selectable). Did I miss a step inside premiere pro to get this option to show up? (didn't do anything inside this software other than open up a new project, and go to project settings)

It looks like we have a very similar machine, based on the specs from your video.

Thanks for posting a follow-up. I am also getting choppy playback but it is with large-format timelapse files.

I'm not sure it is a disk speed issue like yours though, because the video files play fine in Quicktime, and are only choking during playback in Premiere CS6.

But yeah, thanks for telling us how you resolved your issues.
