I agree with John.
Please tell us what operating system you're using as well as which processor you have and how much RAM.
Is your AVCHD video in the .MTS format?
If you place a video on the timeline in Expert view, do you see a yellow line along the top of the timeline?
Have you ensured you have the latest version of Quicktime from Apple?
Thanks for the reply, My operating system is windows 7 service pack 1, Pentium (R) Dual core, 2.80GHZ 2.80, Ram 8.00GB, Hard disk driver (1) with 380GB free .The AVCHD is MTS format, no yellow line on the timeline in pe 12 and I have QuickTime 7.7.4 Thanks Dave..
Your computer is a bit underpowered for AVCHD editing. But, if your project is being set up properly by Premiere Elements (which it is, if you're not seeing a yellow line along the top of the timeline in Expert view), you should be able to do basic editing.
Most likely you've got something in the background interferring with your playback. This could be antivirus software, your firewall or Windows Indexing -- or possibly some background program or even malware.
What antivirus program are you using? Norton antivirus is notorious for dragging systems down.
If you open your Task Manager with no other programs open on your computer, how many background processes does it list as running?
Have you manually gone to Windows Update and ensured you have all of the Windows AND Microsoft Updates, including those that do not install automatically? When did you last run Disk Cleanup and Disk Defragmenter?
Thank you for all your help and input,
I shall check these pointers out that you mentioned, I do have Norton, in your opinion what are the best file format for my computer to run, many thanks
