The comment: Perhaps a good thing to try would be the nice, simple, basic program svv, which you can get from the website of Jean-Francois Moine. Some of these other things do not always work. Especially I have had trouble with xawtv, though the xawtv people may have fixed a lot of problems while I was not watching them. The question: Is this a dual-mode camera which is also supposed to have still camera capabilities? If so, you might be interested in contacting the Gphoto project. I just searched for it there, and it does not seem to be listed. I assume that the specialists on the spca cameras will step forward. I am not one of them, as I said. Good luck.
