When I tried to capture contents from VHS tapes, I got the following error message:
CAP2001--- The USB driver for CapWiz has not been installed. CapWiz will not be able to preview or record video without a compatible USB driver.
There is no way to make the application work in P7 because the website with the drivers does not exist anymore. Some users had this problem but the discussion is 3-4 years old. However, you can download the drivers from a 3rd party website using Google. You can find the drivers on the HelpDrivers.
