My computer (with CS5) edits AVCHD very smoothly
Intel i7 930 CPU with 12Gig Ram and Windows 7 Pro 64bit
Asus P6 SE motherboard with PNY nVidia GTX 285 graphics adapter
320 Gig boot & software drive
320 Gig temporary and project drive
1 Terrabyte video file drive
Codec & Format information, with 2 links inside to read -read both links in reply #1 http://forums.adobe.com/thread/1270588
Report back with the codec details of your file, use the programs below... A screen shot works well to SHOW people what you are doing

XanderICU Dec 18, 2013 3:01 PM (in response to John T Smith)My very nice computer "Details":
Intel Core i7 CPU X980 at 3.33 GHz 3.33GHz - 24 GB Ram - Windows 7 64 bit
NVIDIA GeForce GTX 460
I have 1.7 TB of free space
Video plays fine under available preset AVCHD 1080i25 (50i) after being rendered. But choppy playback under the presets of AVCHD 1080i30 (60i). The only differences being the frame rate of 25 per second vs 29.97 frames per second (drop frame timecode numbering).
The media file format is:
.MTS(AVCHD)
1920x1080
29.97 frames per second

XanderICU Dec 18, 2013 3:20 PM (in response to Peru Bob)Maybe I should elaborate... I'm not editing big files of video... Only short videos...
Unless you are insinuating that partitioning my hard drive will optimize performance, I do not believe my hard drive to be an issue either...

It is most likely the issue. And don't use partitions.
See here for a probable solution:

XanderICU Dec 18, 2013 3:55 PM (in response to Peru Bob)I still don't believe the hard drive to be the issue. Like i said... the video projects I'll be publishing won't be any larger than 500 MB. I don't need to get more hard drives. My compuer should handle this.

John T Smith Dec 18, 2013 5:00 PM (in response to XanderICU)>24 GB Ram - Windows 7 64 bit
CS4 is 32bit so may use no more than 3Gig of ram... and, you MAY need to right click the program icon and select WinXP compatility from the option window for best operation
An EXAMPLE concerning trying to use only ONE Hard Drive for Video Editing
.
You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
.
Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
.
You as a person cannot do both at the same time with the same hand
.
A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for EASY video editing
.
You need AT LEAST two hard drives (separate drives, never a partition for a "spindle" drive http://forums.adobe.com/thread/650708 for more on partitions) with Windows (or Mac OS) and software on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down by trying to do everything... not even with SSD see # 16 http://forums.adobe.com/thread/1352987
.
Do not try to use a USB2 external drive for video editing, the USB2 file transfer speed is too slow
.
External eSata or USB3 are both fast enough for video editing... http://forums.adobe.com/thread/1117813 - http://ppbm7.com/index.php/tweakers-page/84-disk-setup
.
ONE possibility is this $47 USB3 dock with fan http://www.amazon.com/StarTech-SuperSpeed-Docking-Station-Cooling/dp/B0055PL2YI
.
And, some comparison tests http://forums.adobe.com/thread/1144620

Under CS4 read the 6th bullet;

In most NLE its common practice to have a separate AV disk.
What kind of media are you using.
If its H.264 in a mov wrapper you are even more out of luck. CS4 cant properly handle that kind of media. It was corrected in the next version.
