It has to be said that making copies is illegal - full stop.
What people DO do though is make copies of rented DVD's which is a grey area I am told. In that such copies are thus accepted if for your own 'personal use' as is copying CD's, audio tapes and VCR tapes - also 'for personal use only.' I believe DVD Shrink was bought to court in the USA and was given the OK providing it was for PU. However, I cannot claim to be 100% certain of the legalities.
But..............and I am sure of this..........PPRuNe must never be used for the purpose of advising others how to make a copy from a DVD, or anything else for that matter, for anyone other than yourself. We DO have a rule for that and you won't like it. Your own rule in that regard should be to avoid voicing it on here.
