A VHS movie is not 'data'. Look up the definition of data. And just becuae it was widely copied does not mean it's legal.
Sure, but it's not legal. And the reasons you give for copying are all justifiable in some manner, but again not legal. Most people here bizarrely think that just because the movie is now digital they can make legal copies of it. No you cannot. Copying movies to a harddrive is not legal and does not fall under the terms of the oft quoted 'fair use' law.
I understand that you will still argue about exactly what data is, but VHS is an analog format and the dictionary defines analog as: "of or pertaining to a mechanism that represents data by measurement of a continuous physical variable, as voltage or pressure." Further, data can be used to describe a body of information.
Regardless, I do agree that in most cases it isn't legal.
