ok here i can report some sort of success:

i created these 3 videos according to your hints:

catch22bv1200.avi
catch22bv1200.mp4
catch22bv816.mp4

the mp4 play fine the video (no sound but i can care about this later)
but the catch22bv1200.avi does not play at all despite the fact that i just
changed the extension of the output file in the command you have sent me.

i am not sure why. for some reason other avis play fine at this TV. (also
the input for the command was avi).

i will try to experiment next days. if you have any ideas about what could
be the cause please let me know.
