I use similar camera.
I have same problems.
solution:
Use for setting up the camera only "Amcap" a small software that can access the camera or tunner for that matter.

After you set it up it will autosave the settings for freetrack and DON'T open the settings in freetrack again. Or if you do open don't close them with OK... only with "cancel" or "close".
This happens even in 2.2 with windows 7 but I use 2.1 and Win Xp.
