You might need to let the hardware gurus on the forum take a look at your systems specs and setup.
What happens if you use a more standard type "media" from a camera in your projects? ie dv, p2.mxf, AVCHD etc..
Fact your UI has issues indicates something else is really wrong.
My guess ...."bottlenecks"
Tell us your hardware setup, CPU type and disk setup, the version of CS5 and the number of processes running as displayed by Process Explorer (not Taskman). Have you tuned your system in terms of services, UAC, search indexing, etc.?
What is the size of your PNG images (pixel x pixel) and how does that compare to your Sequence Preset (Frame Size)?
Have you Rendered your Timeline?
Just thinking here,
I thought I read where image sequences have a playback bug which has already been addressed in the next update. You may just have to wait for that.
"Have you tuned your system in terms of services, UAC, search indexing, etc.?" No. I would appreciate any info regarding such things.
"What is the size of your PNG images (pixel x pixel) and how does that compare to your Sequence Preset (Frame Size)?

PNGs are same size as Sequence Preset (720 X 480)
Yes, I did try a render. When I render it, it plays back fine. But I didn't think I would have to render with my setup. There is a yellow line above the sequence, which I thought meant that I did not need to render it. The main purpose of getting this 64-bit system, with 8 processors and appropriate video card and CS5 is so that I wouldn't have to render such things.

I just played an SD QT movie and it played fine (with time remapping at 38%). And I played an HD QT movie and it OK too (a little choppiness), but much better than the png sequence.
Thanx, Harm. I'll check it out!
Still image sequences are not particularly well optimized (well, they weren't in previous versions, for that matter). There is a performance optimization specifically targeted at still sequence handling that will be in the next dot update for PPro. It should help things considerably.
Thanks, everybody! I really appreciate it.
A little off topic, but what a difference it makes with smoothness of palyback when I use TIME REMAPPING in Premiere, vs SPEED/DURATION. TIME REMAPPING is much smoother.
