First problem, Easycap is a pile of junk...but now this is tricky there are 2 types Easycap and Ezcap and i have done a lot of research (well a bit
) and i can't tell which is the fake...but you can have a play around with the settings to try and reduce the frame rate. I could get a half decent image using "Am cap" Just go ogle it.
Another point would be too make sure you have decent cables connecting your box and T.v/Laptop
Here is a video i recorded if you just play around with the settings

I really hope this helps
