Please name a technical problem which would result in the same bit of video appearing more than once in a sequence.
If this was someone pressing play+record on an analogue audio-only tape, after fumbling around with fast-forward and rewind, sure! But this most certainly is not that, let's be clear.
This is not a technical "problem". There is incompetence here, I agree, but not the flavor you are suggesting.
This can be a whole bunch of technical problems, or more likely incompetence with uploading it.
