I have camtasia 2 for mac. I am very happy with it. I have a problem you may be able to help me with. Many years ago I had my 8mm movies put on a DVD by a commercial company. I want to capture bits of these movies to make a presentation for my family reunion. When I tried to use camtasia the screen went blank while I had camtasia on. Could you recommend a good "ripper" program? I am very disappointed pointed that this company made my DVD in such a way that I can not use it.
