Hi,

I am seeing this issue on a Quad core as well, the interesting thing is
if I import a single clip into Openshot and play it back it works,
however opening an existing project with many joined short clips from
the same source files results in the playback issues, it is so
pronounced than on many of the short clips only a single frame is
displayed in the preview window.

For what it's worth the files are 1920x1080 .mov files with AVC Video
and PCM Audio from a Canon Digital Camera.  I'm uploading one for the
sake of testing here (May not be finished uploading until a while after
I post this):

Title:
  Sluggish video preview with mlt 0.7.0

Status in OpenShot Video Editor:
  New

Bug description:
  1. Fedora 14 x86_64
  2. RPM (RPMFusion)
  3. Openshot 1.3.0

  I'm the Openshot maintainer for Fedora. I got a but report against mlt
  in RPMfusion that the upgrade to 0.7.0 made playback sluggish. For
  him, 1 frame every 10 seconds. A quick test on my system with AVCHD
  video showed stuttering but still watchable video.

  Downgrading to mlt 0.6.2 seemed to help.

  Is 0.7.0 supported or is it too new? Kdenlive doesn't appear to be
  affected.
