Cannot download movies to computer. Images...

Question

Canon PowerShot SX100 IS:I use the solution software provided by Canon (camerawindow). The images download to computer without any problem. The software starts downloading the images and when it comes to a movie it stucks and crashes. I can copy the movies from the media card (SD card) (through accessing the camera from windows explorer --> My Computer) and paste into my computer. But cannot download using the software. I could be something to do with the movies size. Movies tend to be large in size (~50MB) compared to 8megapixel images (~3-4MB).Do you have any solution please?Thanks
