This makes me think that you're hitting the issue described here:
Try the second solution (the one regarding starting in the root user account) on that page.
This has nothing to do with the Mercury Playback Engine. Once you get past this bug using the solution that I recommended, we can talk about any performance issues that you're still seeing.
Also, be sure to install the Premiere Pro CS5 (5.0.3) update.
Thanks! I have been searching for days and had not come across the link you sent me.
Right after I posted, I noticed the update and ran it. I also deleted that preference file at the same time, and it now plays back footage pretty smoothly. Very impressive.
The Mercury Playback Engine is still unavailable though. I kind of was hoping that would help things run a lot better. Any advice on that? Also, I only have 4gb of ram, and am planning on upgrading to 8gb. Would that help with the MPE?

First of all, it's important to get the terminology straight. Here's a quote from a recent article:
"I’ve noticed a lot of people—the vast majority, really—using the term ‘Mercury’ or ‘Mercury playback engine’ as if it refers specifically to CUDA processing. Not true. The term ‘Mercury playback engine’ refers to a whole set of performance improvements in Premiere Pro CS5, including the port to a 64-bit application, the multi-threaded nature of the application, and the use of CUDA on the GPU to accelerate some things. Anyone using Premiere Pro CS5 is getting all but one of these advantages; people with certified CUDA cards are getting one additional advantage."
Note that your card is not on the list of cards that provide the CUDA processing features for Premiere Pro CS5.
Also, I only have 4gb of ram, and am planning on upgrading to 8gb. Would that help with the MPE?
More RAM would certainly help with performance, though you're still abusing the term 'MPE' in that question.
Thank you so much for clarifying. Sorry to abuse "Mercury Playback Engine". I think it is hard to know what to call it when it is greyed out and the name is too long to appear in the dialoge box.
I really appreciate your time on this and I hope other find this thread helpful as well.
Thanks John. That is the one article that kept coming up when I was searching for a solution.
Unfortunately, unless I switch over to having windows loaded through bootcamp on my Mac, the links windows based solution will not work.
I had been messing with trying to get my own modified version of the Windows tutorial to work, and then just a few minutes ago, found this tutorial
But, when I ran GPU Sniffer, it says I did not have enough GPU ram. I went ahead and added my graphics card to it. Bummer. But that does lead me back to my original question, how did the Adobe evangelist use a Macbook Pro... unless he was demoing it and it was not using hardware acceleration. You know, that is probably the most likely solution.
Thanks guys so much for your insight on this! I think I got it all figured out. Deleting the Preference file was the thing that now enables me to edit DSLR footage. Not fantastically fast, so I may still keep using my FCP with ProRes workflow.
By the way, one tip for greatly improving the smoothness of scrubbing and playback is to set the playback resolution to something other than Full in the Program Monitor. There's no point in rendering every pixel for a preview if the panel is at such a size that a lot of those pixels are just going to get thrown away when then preview is scaled to fit within the panel.
See this page.
For sure. That is something I really like about how Premiere does that.
