I got a bunch of VCR home-recorded movie tapes. All were recorded on normal
commercial tapes, the "autoplay" tab was still there, so it is the normal
tape type I use.

I played several and they are OK. But I played one tape, which looks
perfectly normal, with strange results.

After tape is inserted in VCR, the VCR automatically turns on (normal).
When I start Play, a first movie scene shows, but within seconds, Play
stops, the VCR shuts itself off.

The tape looks normal, no damage, etc.

What is happening here?
