Dash cam software recommendations?

[TNGW1500SE]

I have a PC (running 7) in the RV with a camera on the dash. I'd like to use it as a dash cam and record while driving "just in case". I downloaded Yawcam and can use that program but is there a better option?

I use VirtualDub which is free. You can download it here:

I've never found any reliable un-buggy solutions. Purchased a stand alone dashcam at Costco. Cobra for $99. Been working great for over a year, install and forget, powers up and records when you start.
