Much of this was fixed, if you've updated to version 8.01, Negative. Have you updated using the Adodbe Updater, per the notice at the very top of this forum?
Also, I'm not sure how AMD processors equate to Intel, but most people working with AVCHD are running quad core processors.
The program also benefts from your ensuring that you're using the proper project settings for AVCHD video and frequent rendering. (Whenever there is a red line above the clips on your timeline, press Enter.)
Right now, no AMD processor does well with AVCHD files... according to what I've read in many other messages
Intel i7 works well
You also need AT LEAST 2 physical hard drives (NOT one drive with partitons) with all software on drive 1 and all data on drive 2
3 drives so scratch/temp files are on their own drive is even better
Yes I updated today and I'm still having that playback issue... I
was under the impression that I would need to install another Hard Drive, yet I was trying
to figure out what would be ideal. Should I go for something higher than 7200 RPMs?
A 7200 hard drive should be plenty fast enough -- assuming your processor is up to handling AVCHD video.
When one is running low on resources, there are two main causes:
1.) the system is just not up to the task
2.) other programs and Processes are stealing necessary resources
For #1, upgrading equipment will be job 1.
For #2, this ARTICLE might give you tips on cleaning things up for an editing session.
Also, please tell us more about what seems to be a single HDD. What is the amount of free space?
What is the speed?
As John T. mentions, 2 physical HDD's is about the minimum for editing Video, and three are even better. Can you add more HDD's?
Then, tell us about your Windows Virtual Memory (Page File), how it is managed, and its size.
