(still no audio)

i reduced the ffmpeg options to reduce complexity of this troubleshooting.
you can see that only the change of container avi -> mp4 makes it start to
work correctly. not sure why as the TV played .avi before. just in this
(and maybe few other cases it does not work).

could it be something inside the original avi container what got into the
second avi that could disturb the TV player?

also take a look at the frame count:
mp4 175025
avi 175026

i thought the encoding is the same as: -b:v 1M -vcodec libxvid is used for
both avi and mp4.
still avi has one extra frame....

is it a bug? sorry that i ask i am no expert in this area...

E

ps: if you need the complete terminal output let me know i will run it
again...
