As far as I understand from the description of the technique, these aren't actually VCR/VHS errors - they're RCA line errors: "To discover his glitch art, Johnson plugs short, repeating videos into an Xbox 360 through its USB port, and then feeds that into a VCR. The output is projected on to an old CRT TV he bought from a thrift store. He then manipulates a frayed RCA cable that runs from the Xbox to the VCR while it’s recording in order to interrupt the signal. “The colors tear, images start to warp, and still images start to come alive with organic motion,” Johnson says. “I’ve recently looked into some circuit bending boxes that can be an intermediate between the signal and the recording, but I like the lack of control I have with just jamming some wires together.”" He's using a VCR to capture the resulting distorted video, but another digital device with an RCA input line would work just as well.
