>glitches are still there, just at different places
That usually means there is some kind of software running in the background that "wakes up" once in awhile to check to see if there is anything it needs to do... and every time it wakes up and STEALS the computer's attention, that causes a Premiere stumble

Work through all of the steps (ideas) listed at http://ppro.wikia.com/wiki/Troubleshooting
If your problem isn't fixed after you follow all of the steps, report back with ALL OF THE DETAILS asked for in the FINALLY section, the questions at the end of the troubleshooting link... most especially the codec used... see Question 1
A few questions:
Where are you observing the issues with playback of the Exported material?
What is the I/O sub-system, i.e. your HDD's, their size, speed, controller type, and how allocated?
Turn off the Mercury Playback "Hardware" acceleration and make sure there are no Mac *.AIF audio files on the timeline.
BTW, I'm on show site at the Fountainbleau in Miami with the pressure full on. We have been exporting first with Hardware Mercury turned off. Export as an uncompressed AVI then bring the AVI onto the timeline and export the final mpeg or whatever from that. Mercury Hardware sometimes causes glitches in cross dissolves.
software running in the background that "wakes up" once in awhile
While that could possibly affect live playback, it's not very likely to cause any issues with an export.
How are you viewing the playback -- in Premiere, or in another app?
Hello John T, Bill, Chuck, Jim and Jeremy,
Thank you so much for all the helpful questions/ideas. Sorry for not responding sooner--my email went to the wrong account! By the grace of God, client played back the file for the presentation and had 'no problems'!
One clarification I want to make is this: The 'glitches' problem is only on playback of the rendered/exported file in QT / Windows Media Player. Nothing to do with PPro --other than it created the file.
I apologize I didn't make that clear again, I'm just trying to play back a HD file (mpeg2 / H.264) in QT (ver 7.4.5) or mpeg 2 in Windows Media Player without getting 'glitches'--i.e. very brief stutter/freeze of playback, but nonetheless not acceptable.
I think what John T said could be the culprit:
">glitches are still there, just at different places

This would explain why it happens at different places in the clip on playback.
@Bill, I have a brandnew system--fresh install of CS5--don't think it's a speed relate problem, because I kept making the output movie smaller and still got glitches even on a 4 minute long MPEG2 HD clip that was only 172MB --so I would think the bandwidth would not be an issue.
But I have seen how 'flattening' a movie can help solve a multitude of problems( my experience w/ Avid systems for years showed me that) You exporting an uncompressed AVI , reimport it,then exporting it again to Adobe Media Encoder is what I was trying to do, but couldn't figure out HOW to do it--I will look into that. Thank you!
I am viewing the MPEG2 1280x720 HD movie in Windows Media Player. (not in the PPro timeline--sorry for the confusion)
Several users have had issues, when Exporting to QT files, with the Apple CODEC's, especially H.264. All sorts of issues. Many have had much better luck with H.264 from Lead, or MainConcept. Also, many have had myriad problems with QT Player playback of many HD files, that did not exist in VLC, WMP or MediaPlayer Classic HC. There is something wrong with QT Player, but considering how much Steve Jobs hates anything Adobe, I am not surprised.
