Currently I'm using Pinnacle Studio 11 software and finally got it work with an old Pinnacle PCTV capture card that I found in the cupboard. The card is 7 years old btw, solved the problems I was having. I'm sure there is a modern card from Pinnacle.
The Studio 11 software is brand new and was supposed to work with USB adapters, and it did on an old laptop. I got a brand new PC and it just wasn't right (bad frame frequency, or in black and white, crap resolution etc). The geeks who sold the PC to me were dumbfounded, which is a common thing. So I kept trying different things to fix it and yesterday arvo it all clicked.
