I have a couple of movies on DVD that I purchased along with a DVD player. I have noticed that the price of DVD recorders is dropping to the point where I am seriously interested in purchasing a unit. All of the ads that I see for these recorders offer various numbers of free blank DVDs as an incentive to make the purchase. As one who has never done any DVD recording I would like to know if these DVDs that are used in home recorders can be reused and recorded over in the same manner as Videotapes. Or, is it simply a one shot deal with each blank DVD. Thanks for any responses to this post.
