Q14. I purchased a Panasonic DVD recorder to make copies of movies I've purchased.
My children may accidentally damage the original disc and I'd like to have a backup copy.
Each time I try to copy the disc, I'm unable.

Copyright law prohibits copyrighted movies from being copied, even for person archival use. Panasonic's DVD recorders are designed to respect intellectual property and abide such laws.
Copies cannot be made. Pre-recorded video tapes and DVD discs on the market are not able to make copies.
