I tried installing the latest version of zs4 on windows xp and the installation failed.

I was able to install the earlier version 0.956 successfully.

I'm not getting far though.

I have a video from a Fuji digital camera that I mistakenly short in portrait mode and I wanted to rotate it 90 degrees, hopefully without distortion (Windows Movie Maker distorted the video when I rotated, which is why I am looking at other video editors).  I pick the video with the file tab (it is an avi file).  But in the import tab the playback buttons are disabled.

I figured that I should try some other avi file and see if I have the same problem.  So I tried loading 2 different avi files from my Sony mini-dv camcorder.  In the import tab in both cases, the playback buttons were enabled, and I could see some progress for analysing the files.  But for the first file, the progress stopped at 89% and for the second file the progress stopped somewhere in the 70% range.  Using the play button, the first video kind of played, but there was no audio and the video was very choppy, kind of like jumping from one still frame of the video to another still frame of the video.  The second video just played a few frames and stopped.

Assuming that I can get the video from my digital camera to play at all, I need to be able to play the video files smoothly with the audio to know where to trim the beginning and ending off.  With no audio and choppy video, I cannot get anywhere.

Can someone tell me what I'm doing wrong?
