The original VHS tape must be over 21 years old now as I taped it from BSkyB's The Movie Channel, which rebranded in 1997. I'm not sure whether I taped it from BSB's original Marco Polo satellite or from Sky's Astra though. Probably the latter as my BSB receiver and 'squarial' became redundant at the end of 1992 and I took advantage of a year's free 'dual movies subscription' compensation offer soon after when I replaced my system with a Sky analogue system in early 1993.
I will not make any further copies though - I only made my own DVD-R for 'format convenience' in case my VCR died and anything else would undoubtedly infringe copyright.
