Welcome to Adobe Forums.
It might be an issue with incorrect settings.
If you are working with high definition video, click on file>new project and choose a high Definition Preset.
For ex if it is an AVCHD footage choose the preset as AVCHD. Also if you are on Windows machine, please
update your display driver and then check.
You are right that the lack of line indicates no rendering required, confirmed by [Enter] going straight into playback mode. This also suggests that the project preset is correct.
If you know what your clip settings are you can confirm this by comparing to Edit> Project Settings> General.
What PRE version? What Operating System and Version?
More likely the problem is machine related:
- How much RAM?
- How much defragrmented free disk space?
- Do you have the latest version of QuickTime installed?
- Are your graphics card drivers up to date?
- Do you have lots of other programs running at the same time?

I'm with Neale. It sounds like your system may not be powerful enough to handle your media.
My laptop is 5 years old so I cannot expect to much.
I have cured the prob by adding a option like flicker remove or any other work I do on the timeline, it will come up with yellow line indicating that it need to be rendered.
Thanks for help
Are you saying, once you force the clip to be renderable (in your case Flicker Remove applied) and then rendered the clip, that the jerky playback was gone?
If so, what is the brand/model/settings for the camera that recorded this video.
My question goes to my observation a while back that some Canon video had to be forced to a renderable state (I used minor Time Stretch adjust) and then rendered in order for the clip to playback OK in the Edit area monitor.
Looking forward to your details if you have the time.
Good work in curing your problem.
