Hi! Do you have mplayer installed ? It looks like that canola is using mplayer to play your videos. When it uses mplayer, it stretches the video because we give a window to mplayer (we should correct this with a patch for mplayer). On the other hand, you can edit the file /home/user/.atabake/config and change the option "video = mplayer" to "video = oms". Than canola will use oms to play your video files and they'll not be stretched =) Thanks,
