Camera records video smooth in Camtasia 8, but choppy in Camtasia 9. Using Logitech Webcam Pro 900 with Windows 7. Updated camera driver, and made sure other programs are closed (just in case, with no change). A solid desktop, with plenty of power and memory. Still have Cam 8, and may have to stay with that version, if I can't resolve. Thoughts? Any way to correct?
