You can't use a Pinnacle device to capture in Sony. It will only work with Pinnacle unfortunately.

What are your computer specs? Your video card? How much ram? I know you said you looked around on the Pinnacle board, but did you actually post your problem.

Make a post with the heading "710 USB freezes after 2 min capture" and then make sure you fill in your user profile. Let me know if you have done this, and when you post - and I will personally ask several of the senior people to help you. But you have to be willing to give the information so people can help you.
