I wonder if I could ask people for some advice on a technical issue. I have recently discovered that a number of pre-recorded VHS copies of films in my possession have become impossible to view, the picture perpetually blurred as if there are two images. Oddly, this doesn't seem to be happening with recordings I have made myself. These items age from two to several years old. In some cases I have watched them more than ten times, I suppose. In other instances, not that often. As a Film Studies teacher, I have used the 'search' facility quite extensively. A key example in a textbook I am writing, one of them has been searched very extensively and is now particularly difficult to view. I realize this is not really the place to be pitching such queries, but if anybody has any thoughts I would be interested to hear them. I am aware that video degrades, but not this quickly surely! Although I have a DVD, I was not envisaging replacing 100s of videos so soon! Thank-you for any insights... Richard
