    Bleed needs to be fixed in the analog domain, if possible.
    I'm sure you already know that, however...

    Desaturation is sometimes the best alternative for this problem.
    Lesser of evils.

    There is an old vdub plugin called flaxen vhs filter
    http://neuron2.net/flaxen/flaxen.html

    But there are more choices/control in avisynth; if you do a search at the doom9 forums you will find many filters , maybe one more suited to your specific problem

    The problem is the so called "two way colour bleed"!

    AFAIK, this occurred when local channels use to rebroadcast other ones, from analogue satellite feeds or terrestrial links. Something during the signal passthrough, created a 3 layer colour bleed, which is typical of the RGB connections.
    So it was broadcasted wrong to begin with...

    Another situation is when they have to convert from NTSC to PAL, or PAL to SECAM. The converted results had usually some colour bleed (because they used tapes to store the results for broadcast), that normaly nobody could see back then.

    I can fix the colour bleed of my VHS tapes with hardware easy. But what I wish to try to do, is to fix that colour bleed of the original source. I can try to do this only with software.

    One is certain: Commercial VHS and home movies have much less issues than the homemade VHS tapes, recorded from TV.

    I do desaturation, with a 2 step filter chain and always after neatvideo: Exorcist (Ghost Shift 1 or 2 / Ghost intensity -38 ) and then brightness/contrast (0 / 175%). Sometimes "Autolevels 1.2" at the luma space can work better than Brightness/contrast, but it can easily also do harm, so I avoid that alternative for videos with many dark scenes.

    Thanks poisondeathray for reminding me the flaxenVHS. I had years to use that!
    Avisynth is not for my case for various reasons.
