Imagemixer by Pixela does not work at a satisfactory level. The video is fine, try to download SMPLAYER for Windows. It is an open source software. This will be able to play the .MOD files from the camera. If you have an SD card reader, you can copy the files from the SD card to the computer, this will be faster than importing via Imagemixer. If you want to edit, there are video editing software which use the SMPLAYER engine.
The MOD file format used by Canon follows the same format used by JVC for their hard-disk cameras, among other camera manufacturers. Linux has more tools to play this format, as well as to edit the videos. Maybe because of the open-source community support.
Enjoy the camera, I have a Canon SD camera myself and I am very happy with it.
