Faint vertical lines from VHS thru DVD

    When I play VHS through an extension source of my DVD recorder, in order to
    copy that VHS to disc, I am getting faint vertical bars moving rapidly
    towards the right of my screen during playback of the VHS. When I look at
    the VHS through the regular VHS source these lines are not there. Can
    anybody help me solve this problem?.

    I have checked all scart connections, have replaced some of the scarts but
    nothing works. I do have a digital input through the same source on the DVD
    recorder in which the VHS is going through, but I removed the digital to see
    what happened and the problem was still there. It is something that has only
    happened recently and was not there before. I hope somebody can help -
    thanks in advance.

  2. Possibly breakthrough from the tuner if you've got one fitted in the DV
    recorder. Try selecting a channel with no signal or unplugging the
    antenna & see if that cures it.
    VHS frame & line rates aren't controlled very tightly compared with
    broadcast specs, so they give this effect.

    Tciao for Now!

  3. This is very common and can often be fixed by using a higher quality
    SCART lead with fully screened video coaxes or via a simple
    modification to the existing lead. The usual cause is the tuner in the
    DVD recorder, which is outputting off-air video out of the same SCART
    socket that you are inputting your video from the VHS on. The off-air
    video cross-talks with the incoming VHS video due to poor cable
    screening.

    Unless you have a requirement to record the DVD recorder's off-air
    video onto your VHS, the no-cost solution is to open up the SCART lead
    at the DVD recorder end and snip the wire going to pin 19. This will
    isolate the tuner video from the cable.
