State Univ. Lines: 39 In response to your questions: [1] Any dubbing of a tape is going to reduce the quality of the destination copy. Based on the fact that the home recorders do not generate a Broadcast quality control pulse (sync) you tend to lose picture stability when you copy. (unless you process the signal through a Time Base Corrector which cleans up the control signals and costs much $$). Yes, the speed at which you recorded the original will effect the quality of the copy. Copies made from the highest speed will be acceptable, while copies made from a slow speed will be very unstable. [2] Making a copy by modulating and remodulating your signal will seriously degrade your picture quality. If you want a best possible (given the quality of your equipment) copy spend the money on video patch cords, it will be well worth the money. They are not excessively expensive. (If you have BETA you need a BNC->BNC connector for video and an audio cable that will vary from machine to machine, usually a 1/8" phone plug to 1/8" phone plug) (if you have VHS you need an RCA phono -> RCA phono for both video and audio -- this is a standard plug such as that which is used for connection between stereo components -- It has been my experience that the VHS machine RCA jacks are somewhat picky. If you cannot get a good connection at the plug keep plugging it in and you will eventually get a clean signal) Sorry this has been a little long, but I wanted to get the straight facts clear. If anyone has any other specific questions concerning eqiupment that they do not want to post to the net I would be happy to correspond via mail. Mark L.
