I am trying to copy a DVD disc to a VCR, but not having much luck.

When I first purchased the DVD-R, I did copy several to the VCR then as I copied back to a DVD, I was able to edit sections, as I viewed it on the TV. But now for some reason I forgot, or am unable, to view it on the TV as it is being copied back to a DVD. Sections of the original I like to delete before giving it out to family.

These disc are not commercial, nor are they copy-protected.

If anyone has run into this problem and has a suggestion I'd appreciate knowing how it was resolved.
