As the title says I have tried the Mux programs here that I found and they all seem to fail.
Any Suggestions that would work quickly without my needing to re-encode them ?
Thanks in advance for any help

The .mp4 container doesn't normally allow for .mp3 audio. Either mux it as .mkv or .avi -- or just bite the bullet and convert your audio to AAC. It's very quick.

Then you should have said exactly that, instead of saying:

P.S.: please stop trying to "prove" that I am "always wrong", because you will always fail at that."Programmers are human-shaped machines that transform alcohol into bugs." -

@TBoneit - I would recommend first to show us a MediaInfo analysis of both streams, instead of converting (with quality loss) right away. It is indeed possible that you e.g. only believe to have MP3 audio, but it is instead a different format, and VLC only plays it because it doesn't rely on the filename extension only, but checks for more details to identify it. Similar guess for the video stream.
And I agree with El Heggunte: The MP4 container will of course support MPEG Audio streams, from MPEG 1 Audio (at least Layer 2 and 3) to MPEG 2/4 AAC variants. Whether a specific player supports any combination is not the fault of the MP4 specifications, but the implementation in that player's firmware. The MP4 container even supports a few non-MPEG audio formats (PCM, AC3). -
Here is what I see in Mediainfo

I hope this can pin down why
Many Thanks

Not really. I was curious about the analyses of the separate source files, not of the multiplexed result. This one contains AAC audio, not MP3 audio.

Hello
Those are the results of the Two separate source files. One is audio only and one is Video only. Why they do not want to mux in mp4box is beyond me. I have used it in the past and it worked.
FWIW the Video file extension is mp4 and the audio file shows as mp3, Could that be the problem ?
Thank You

Like others said AAC in MP4 (specifically stereo LC-AAC) has very good compatibility so that's good news.
If you fail using mp4box try ffmpeg as already suggested:
Code:ffmpeg -i "videofile" -i "audiofile" -map 0:v:0 -map 1:a:0 -c copy "output.mp4"
Never shorten MediaInfo logs to just the track info. Container info is equally important. As are logs of e.g. mp4box/ffmpeg if something unexpected happens.
