A very strange thing is happening to me in blender. I recorded footage from cca 10 years old camera (can't tell you the type, don't remember). The footage was 25fps, original dimension 1440x1080. I set up the blender environment according to youtube video called 1 - Blender Video Editing (Setup Defaults) by Mikeycal Meyers and started inserting my clips.
As the tutorial said, I was supposed to match the dimensions and fps of the original with the settings in Blender. But when I changed the Blenders Preset resolution of 1920x1080 to my needed 1440x1080, the video got squeezed from right and left, leaving the picture squeezed and therefore useless. So I changed it back, hoping it wouldn't matter (but it may affect the problem I'm about to describe).
I had footage that was all taken from one camera under the same settings. When I took pieces of the recording and cut them in Blender, after rendering, in a few of these cuts the video is twice as fast as the audio. The rest is fine. Later, I deleted and inserted the "wrong" pieces again. The strangest thing is that one day it rendered fine, and a few days later the latter clip got rendered wrong again.

second cut is wrong - http://www.filedropper.com/8700-9921
Could you tell what went wrong from this?
Would be very grateful for a solution, this has taken many hours already...
