Per Jim's request, I am posting this here:
After successfully creating one DVD using Videowave and 40 minutes of clips into a second one, the program now crashes on me every time I try to add a single clip. A defrag did not help. I tried a clean install, and I got an error message saying that I do not have permission to fully uninstall (I have never gotten that before). I then restored the system and tried installing the 9.1 update, and I got another message saying that the certificate file is missing or corrupted. I am not sure what to do as I don't want to lose my work. (My next step will be to update the video card drivers and DirectX.)
I know that the Videowave crashing is a common problem, and after extensive online research, I have not been able to find a "cure." But perhaps I am not understanding everything I read. I do not have experience with these kinds of problems.
I have a Dell Dimension e520, Vista OS, 200GB hard drive, 1 GB memory, and a Pentium Duo Core Processor. We have never had a single problem with this computer, which is 18 months old. I am beyond frustrated. Thanks in advance for any and all help.
