Hi! ^_^
I've an old Pinnacle card too, the Pinnacle PCTV 110i, and Windows 7 recognized it automatically without problems, just like in the screenshots you've posted before.
Maybe you're having problems with some video filters that normally comes bundled in codec packs (like FFDShow, for example, it gives me headache in the past

). So, if you've a codec pack installed on your Windows 7, uninstall it, try to open your favorite TV application and see if the problem is still there.
Good luck!
