In my opinion, Pinnacle...
1) is hard to use, you just jab the wrong commands
2) makes captured video files too big
3) reduces the picture quality, best seen, for example, in still images from TPM (THIS has been made with Pinnacle)
I do have another capture equipment. I don't remember its name and it doesn't work with Windows Vista as far as I know. Plus, I don't know where you could find it because I bought it from a convenience store here in Ylivieska, Finland.
