I don't think you've given enough information for any body to help really. When you say 'play' do you mean that you are previewing your timeline? It may be that you have got your preview set at too high quality and your computer isn't powerful enough to cope. If this is the case, then try producing what you have got on the timeline and only then play the resulting video. Does that play correctly?

If I am guessing incorrectly then perhaps a screenshot of your timeline and also the dxdiag.txt file from your computer may help.

When I say play I am previewing the timeline.



I tried several qualities including low and got the same thing.



My computer is an i5, windows 8. I don't think this is the problem since a preview of a video runs fine as long as i don't try to cross over from one to another. A single video has no trouble playing. The problem is moving from the end of one to the beginning of another.



Producing the video is not going to help. Even if that works, the problem prevents proper editing of the clips.



A screen shot won't show anything, except two videos in the time line? What is and where do you find dxdiag.txt file?

I've taken a video of the problem. Attached.



About 2/3 of the way through at about 2:00 on the time line, the timeline marker stops, and the missed sound starts. When it catches up to the video, the time line marer starts moving again.

A screenshot sometimes paints a picture that words have failed to describe

Re dxdiag - have a read through this thread the 4th post and that will explain.

Did you try actually producing a video to see what the end result is like. Your video looks to me as if your computer is 'running out of steam' when it's trying to display the live preview.

I produced a video - mpg low resolution. When viewed in the Produce screen (I assume this shows the produced video) it hass the same problem as in the preview described above. When I open the produced file in Media player, it has only sound - no video.

I also produced a wmv file. the preview had problems, but the prodeuced file seems to be OK.
