We'll need to know a little more information before we can help you, MrB.
What kind of camcorder did this video come from and how did you get it into your computer? When you started your Premiere Elements project, did you ensure that the project settings match your camcorder footage? If so, when you place your clips on the timeline, there will NOT be a red line above your clips. Is that the case?
How fast is your computer's processor and how much RAM do you have? What operating system do you have and how much free, freshly defragmented space is on your hard drive?
Are you using a desktop or a laptop? Are you editing to your C drive or to a second or external hard drive?
The Camera I have is a Canon Vixia HF R100 and I downloaded the video clips from the SD card onto the C drive. I am using a Dell Laptop with Windows 7 with 4 gigs of ram and intel celeron 900@ 2.20 GHz.
When I look at the properties of the Video clip it said AVCHD Video (.MTS)
Thank you for your help.

It will highly unlikely that you will ever get smooth playback of AVCHD material, with that CPU.
A fast Quad-core, or i7, is about the real-world minimum.
Sorry for the bad news,
As well as what Hunt said, here is information on the "real world" requirements
This message has a really good graphic about requirements
CS5 Requirements http://forums.adobe.com/thread/810750?tstart=0
This is about CS5... but my AVCHD editing is very smooth
My CS5/AVCHD 1st Impressions http://forums.adobe.com/thread/652694?tstart=0 includes a link to the computer I built... since the GTX 285 is no longer sold, I would now go with a GTX 460 or whatever is the current "best bang for the buck" - AND I would buy 4Gig-by-3Sticks memory to be able to expand from 12Gig to 24Gig if needed
For my home hobbyist, family movies (which means that I am not trying to recreate Star Wars with video effects or many layers) AVCHD editing is "as smooth as spreading warm butter on hot toast" (also the MP4 video from wife's Flip camera)
My 3 hard drives are configured as... (WD = Western Digital)
1 - 320G WD Win7 64bit Pro and all program installs
2 - 320G WD Win7 swap file and video project files
3 - 1T WD all video files... input & output files
Yep. I agree with the others. There's no way a Celeron will be powerful enough to edit that type of video. Sorry.
