... Not a surprise there, already covered in my original post:

 To be more precise, FFmpeg versions older than 2.5
not only cannot fetch the AppleHLS streams associated
with the "hvf" modes, but they are also incapable of
performing the lossless remux from the MPEG-TS
container to the MP4 one (for the hvfmodes only -
hlsmodes still work OK) !
 If you have the standard 2.94 install on Windows,
that one uses FFmpeg 2.2.3_x86 binary.
To end up with .mp4 files even in the case of hvf tvmodes,
you should upgrade your windows ffmpeg binary.
(you can download the latest point release, 3.0.1,
courtesy of zeranoe, i.e Kyle Schwarz, from following link:

https://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-3.0.1-win32-static.7z

unpack and use provided ffmpeg.exe (inside bin folder)
to in-place-update the GiP one - or you can point GiP to
the path of the new binary via the --ffmpeg option...)

Cheers,
