VCP-2002 Video Copy Processor

for DVD, S-VHS and VHS

VCP-2002 Video Copy Processor
Due to lack of standards, the muddled situation regarding copy protection and the relatively high price, buying a DVD recorder is not yet recommended. Analogue video recorders are sure to fill this gap for quite some time to come. However, they can only be used for tape-to-tape or DVD-to-tape copying if certain interference signals are removed.Analogue picture recording is slowly but gradually being replaced by its all-digital equivalent. We should emphasize ‘slowly’ because the changeover is hampered by the cost of DVD recorders, blank DVD disks and the insecurity about recording formats to be adopted worldwide. It would be gross mistake to claim that analogue video recording is dead, on the contrary! Excellent S-VHS recorders can be bought for around £ 150 and even if you take into account the slightly higher cost of tapes, the total cost/performance balance of a modern S-VHS recorder is still very attractive.
