Octave aviread problem

[denizyazgac]

Hi. 
My problem is about video pkg.
I just save an AVI and try to capture it frame by frame 

   Filename = speed.avi
    FileSize =  471818
    FileModDate = 01-Jan-1970 01:00:00
    NumFrames =  90
    FramesPerSecond =  29.970
    Width =  1366
    Height =  768
    ImageType = truecolor
    VideoCompression = msmpeg4v2
    Quality =  100
    NumColormapEntries = 0
    AudioFormat = adpcm_ms
    AudioRate =  44100
    NumAudioChannels =  2
    Title =
    Author =
    Comment =



CODE:
clc
clear
pkg load image
pkg load video
for i=1:1:90;
image = aviread ("speed.avi",i);
imshow(image)
pause
i
refresh
end

problem is for consecutive 10 parameter for i, same frame in imshow
after each 10 frame (i), imshow refreshed to the actual frame.

And i tried it without for loop as well. I try to read frame number 10 and
11 and 12 nothing change till 20.

What is the problem?
