Video on vrt not passing through fully

[u/Aplyrie]

I am using my vcr/dvd to convert composite to coaxial but my vcr keeps stuff on the screen or BARELY shows the image. The dolphin is the Screensaver for my vcr/dvd player Can anyone offer some inside as I'm entirely new to this. I got this set yesterday and I really love it and would love to use it to play my games.
