My guess would be that it's exactly the same issue that caused your previous issue with poor preview quality.
For some reason your operating system or hardware is failing to interface effectively with the program.
Steve, I just changed the track size from "small" to"medium" and that helped the timeline issue a lot....I would think that the larger a timeline size, the MORE sluggish it would get? On the issue of preview quality- the preview isn't horrible. It's just not as nice as when it is played with Windows Media Player. It's like some details aren't as sharp The PE Preview seems to struggle with what line to put the pixels on - Like when a reporter has a checkered shirt on. It is more a wavy than a sharp or jagged appearance. Is there any way I can share the video clip with this forum? Thanks. Elwood
Do you happen to be using a Toshiba laptop? Because my computer does a lot of what you described--video is bad quality, the timeline is slow and my clips always come up as unrendered, even though I'm using three different types of camcorders...I have a triple core phenom with 4 GB ram, but it isn't much better than my old laptop...

I assure you guys, your experience is by no means typical.
I'm working on a computer that runs a fraction of the power and and have never seen problems like this!
Wish I had a solution, though, other than to call Adobe Tech Support.

Are you saving all your project files on a different internal hard drive to the captured video files? If not it will be sluggish.
Best is to have 3 drives. OS & PE9 on a smaller C, Video on a large E, Projects on F.
I turn off the timeline thumbnails except briefly when I really need them. You dont really need them most of the time because they only give you a rough idea of where you are and they are the chief cause of sluggishness particularly if you are looking at a large slice of time. In case you haven't found it, it is very quick to change the number of thumbnails by clicking on the little frame icon to the left of "Video 1"
If you select the thubnail option that shows one only at the start and end of each clip this is usually all you need.
The reason it is better to have big thumbnails is because there are fewer of them when they are larger
For zooming the timeline in and out, the slider at the right is virtually instant on my old Core duo with 3gb ram. When zooming in, position the cursor first then move the slider.
I always use the space bar with my left hand to start and stop the preview, This frees up the mouse to be at the next spot far quicker.
I've tried turning off thumbnails and that helps a little. As far as using three hard drives, I have my OS and PE installed on my internal drive and I put my video files and the projects on an external HD. Also, it usually takes a second or so when I push the play button on a rendered file and from 4-10 seconds on unrendered files.
If that external drive is eSata or Firewire 800 you are OK... if USB, it has too slow a transfer rate for video editing
Ted, thanks for the tip about thumbnail settings. I think it helped some! I have my drives configured as C:O/S PE D:media/storage E: projects/rendered clips. How important is it to have E set up as media? Or is it? My BR/RW drive is L instead of the usual D. This was a custom built "video editing computer", and I picked the drive letters the way they are set up. Thanks.
Ah. I am using a USB hard drive (in fact, it uses mini USB ports). However my computer does have an esata port and I plan on buying a portable hard drive that has esata also. Thanks!
