No worries. It is why I'm using Manjaro (an arch derivated) because I have
arrived at the same conclusion. For sample, watching the same video on
SMplayer on the both system and you notice a different result, perfect on
Manjaro.

You should use/try FFmpeg and not his fork (like now). It will be removed
OS and all software using it but after you could reinstall them easily.
Take a look at this thread :

Title:
  OpenShot crashing when saving project, then using the timeline or
  controls to set playback position

Status in OpenShot Video Editor:
  New

Bug description:
  CPU: AMD 64bit 8 core cpu
  OS: Ubuntu Linux (64bit) Raring ringtail upgraded online from 12.04LTS; 12.04LTS installed from ISO.

  Installed OpenShot from "Ubuntu Software Center"
  version 1.4.4~alpha1

  Melt: 0.8.8
  FFMPEG: 0.8.6-6:0.8.6-1ubuntu2 insstalled using "Ubuntu Software Center"

  What's odd is I think this is both an OS level and higher library bug(s). Occassionally the entire OS will hang with the mouse cursor will still work, but the graphics seem to be frozen. Getting loads of segmentation faults from OpenShot when...
  Saving the project, then going to the timeline or video controls to set the current playback position, or advance back to the beginning - pretty much any change in the videos position = instant crash. If I reload the same project after saving it, without changing the current playback position, I have no such problem until I save and immediately try to change the timelines position (seems to be something with that entire process). Oddly enough, I could postone the "crash" by saving, adding a new track, then setting the playback position where-ever I wanted. Worked for awhile, but then crashed after every save again.

  On the OS side, i've noticed on a slower single core system (1.8
  processor), if I click an control or option anywhere in OpenShot (or
  anything for that matter, ie.,. audacity) and don't allow the previous
  function to complete... the applications hang. It's like a messaging
  sync problem with the underlying libraries (doesn't wait for the
  current function to conplete before attempting the next one).

  Also, the first video I made with OpenShot a month ago, didn't exibit
  these problems. It seems to have started within the past 3 weeks
  (perhaps during the upgrade, or with an underlying library not quite
  in sync with the layers above).
