Those VHS to DVD recorder have or were forced to prevent the copy to DVD of copyrighted tapes. This would best be accomplished with a USB type plugin that accepts composite video inputs. A desktop might accept an internal videocapture card but some hardware problems abound. I use the Funai stand alone to do whole copies of VHS-C tapes to DVD, once on that media it can go to any number of machines to edit, mix and reburn to DVD. there are some devices that will allow you to work around the copy protection but that is fraught with problems too.
