Live video cache problem

Hi all,

I have a problem with my GUI program to record video from a camcorder. The program is working fine: live video, recording and saving the movie works perfectly, but when I did it a couple of times, MatLab starts to show less frames per second or just the first frame and than nothing happends.

proces of the program:

1. Item one Show live video to place the camera correctly or the object
2. Item two Record frames
3. Item three Stop and start live video again (back to step 1)

I think it has to do something with the cache of MatLab, but "clear all" en "close all" doesn't seem to work in this case. Only option is to close MatLab and start it up again.

Thanks in advance!

Daniel
