Dragonpic, I've been playing around with Impossible's films. I had many problems with the color film, the silver seems to work best for me but it is also sensitive. The color films IMO are extremely sensitive to light and temperature, so I don't think from what you are describing it is your camera but what is happening to the film as this is similar to my experiences. Try using a light shield (Impossible has some ideas for use with the SX70 on its site) and see if you notice a difference.
