    Trouble playing back timeline


      Frustrating problem playing back timeline.  I can

      scrub and see the video just fine.  Hit the space bar and nothing.  Works okay on bootup but if I leave

      the editing mode for even a few seconds, the timeline will not play.  Currently have Performance based playback.  12GB memory allocated to PPro CS5.  Thoughts?  Thanks.

          Welcome to the forum.


          First, what are the full specs. of the source footage?


          What is the Sequence Preset and what color line do you have over the Clips?


          Can you give us the full specs. of your computer, and especially the hard disk drives?


          Last, you say that things work upon reboot, but over just a little time, things no longer work. What programs and processes load at bootup? Task Manager (on Windows) will give you most of those, and other utilities will go into much more detail.


          Good luck,

            BTW - my Encore will not work at all and I have reinstalled.  It chokes on any file type I try to import.  That's another story.
