Duping from Tape or DVD

[Larry Dodge]

I made a 2 hour DVD and a VHS tape of some home movies for someone using
a  Panasonic desktop recorder.

They now want another DVD copy but they recorded over the original DV
tape so they only have the DVD and VHS Tape.  Which would be better to
record from the DVD with more resolution but compression or the VHS tape
with less resolution.  I have always wondered about this.
