>using a .ts video file
What is the source of that file, and is it HiDef? (I don't use .ts files, so am not familiar with the type)
Did you make sure your project sequence and the file match?
A FAQ on sequence setting http://forums.adobe.com/message/3804341
If that file is HiDef, your laptop is VERY weak with only one 5400rpm hard drive... you need at least 2 hard drives, and your video file drive needs to be 7200rpm
If your laptop has USB3 or eSata... use an external drive http://forums.adobe.com/thread/1117813
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 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
Also, for Windows, I think 6.03 is the current version
