Why do newer VCRs seem to be worse with respect to flag waving?
(From: Jeroen H. Stessen (Jeroen.Stessen@philips.com).) The head fault used to be specified +/- 10 us, then it became 16 us, 20 us and I think we have already seen 22 us. Sooner or later a TV will not be able to follow such large phase jumps before the picture begins. Some TVs can be modified and some can not. The problem is that the line deflection circuit CAN NOT instantly follow a large phase jump, the output transistor would be destroyed at once. It HAS to be distributed over a certain number of lines. You can only hope to distribute the phase jump evenly over as few lines as possible and that there is neither overshoot nor tail to the response. YMMV. It is logical to see more problems on old tapes or on tapes that were recorded on another machine (especially rental tapes) because the phase jump has everything to do with mechanical tolerances and tape stretch. It should be much better on a new tape that has been recorded on your (his) new machine. Macrovision anti-copy protection o
