 I hope this report helps.

 '''Needed: Some way to upload 00001.018.m2ts (4,505,960,448 bytes).'''
 (Upload to 'https://streams.videolan.org/upload/' failed because there's a
 1 GB limit.)

 Source file:
 00001.018.m2ts (4,505,960,448 bytes)
 -- Initial 18:35 of "Patton" blu-ray --
 fails as outlined below.

 (Note that this file: 00001.017.m2ts (4,255,629,312 bytes) -- Initial
 17:23 of "Patton" blu-ray -- does not malfunction.)

 Attached:
 - 00001.018.1.LOG
 - 00001.018.m2ts.Startingnewclusterduetotimestamp.PNG -- [PE] Screen shot
 at "Starting new cluster due to timestamp".
 - 00001.018.m2ts.Cannotallocatememory.PNG -- [PE] Screen shot at "Cannot
 allocate memory".

 =====

 Computer:
 Windows 10 1803.
 Physical memory: 32 GB.
 Disk: 1 TB, SS RAID-0, 562 GiB free.

 Key:
 [PE] is Windows Sysinternals, Process Explorer
 [MPV] is MPV player (Windows)

 '''Processing Events:'''
 [PE] Initial memory use is approx. 650 MiB.
 [PE] Memory usage climbs from there.

     Private Bytes: Rises steadily to approximately 123 GiB (Note 1).
     Working Set: Stabilizes in 23 to 25 GiB range, up-down-up-down (Note
 2).

 [PE] ffmpeg.exe runs 33 threads.
 [ffmpeg] Displays continuous series of "Starting new cluster due to
 timestamp" when [PE] Working Set reaches 8.8 GiB.
 [ffmpeg] Displays "Error while filtering: Cannot allocate memory" when
 [PE] Private Bytes reaches 123 GiB.

 (Note 1) Since these allocations exceed the amount of physical memory, and
 since I saw a process named "Memory Compression" open-close-open-close, I
 assume that Private Bytes means virtual memory.
 (Note 2) I assume Working Set is physical memory.

 '''Playback of 00001.3.MKV:'''
 [MPV] 00:00 - Total time starts at zero (instead of 18:35) and rises by
 about 2x(Running time).
 [MPV] 03:24 - Video freezes while audio continues. (Total time reads 8:24
 at this time.)
 [MPV] 08:24 - Running time reaches Total time. Total time begins rising
 again, keeping 1 second ahead of Running time.
 [MPV} 16:37 - Abruptly closes (early).
