Request for advice on Video Capture devices...

I have a video editing program, Studio Plus (v 10.8). I have been trying to figure out how to copy home movies into digital format so we don't loose them. Turns out the program doesn't work with just sound and S cable. It needs a video capture device to turn analog to digital. I don't know which device to use. Here are four on Amazon. Can anyone give me advice on this? (Or any other advice on this process?)

From least to most expensive:

EasyCap USB 2.0 Video Capture Adapter with Video Editor Software

Diamond VC500 One Touch Video Capture Device

Dazzle DVD Recorder

Belkin F5U228 Hi-Speed USB 2.0 DVD Creator

Alternate suggestions welcome too on both hardware and software.
