Backing up VHS

I want to back up some of my VHS movies, I have a couple of classics that my grandfather gave me like The Godfather series. When I try to do this with 2 VCR’s the image seems to be pulled to the side in sections and the colour seems washed. Is there a way I can get past this?
Cheers

The tapes are encrypted. The vcr sends out an extra signal that the 2nd vcr sees, but the TV does not. If you can find an older vcr, like mid 80s or older, they do not use encryption. Heard RCA is a good one. You can buy a device to strip the extra signal, on the internet, but they are expensive.
