Playback speed very fast for one scene?

Attached is a clip that speaks for itself. The first few seconds show normal playback, everything on this tape plays normally until the next scene in the attached clip which plays back at a high speed, like chipmunk voice speed. The image also seems to be distorted.

1. What causes this? I was thinking maybe the last scene was recorded in a different mode (e.g. SP/EP). I tried switching modes on the VCR but as soon as I play the tape it forces it back into SP. The tape itself is labeled as a Memorex Pro HG 120 with the options SP, LP, SLP. I don't know anything about how it was recorded back in 80's though unfortunately.
   
2. Is there a way to capture this with correct timing? If not, do I have any chance of getting this to a somewhat tolerable state with post-capture editing?

The speed switch on a VCR is only for recording, not playback. During playback it always tries to auto-detect the speed. But it can take a few seconds to catch up to a speed change, so if a very brief scene was recorded at a different speed than the rest of the tape, it might be played at the wrong speed because the VCR didn't have enough time to react to it.

You only gave a short segment of the incorrect speed clip. Does the speed eventually correct itself?

If the recording is EP/SLP perhaps your VCR cannot play that very slow speed.

Thanks for the replies. I do forget the speed switch is only for recording, I always think of switching the speed on a record player.

The whole segment is only about 50 seconds long. The speed does not ever correct itself.

I am using a JVC HR-S9800U.

I was wondering if this could also happen if say someone tried to copy the recording from one tape to another and the tapes or VCRs had different recording speeds? Given it is only 50 seconds long, I was starting to wonder if maybe there is another tape in my collection of home videos I have not gotten to yet that has the original recording if someone did try to copy it at some point.

Maybe it's a VP speed recording? That was Panasonic's odd, proprietary, extra-slow VHS speed that they mysteriously introduced in the 2000s:
