Err... You say -ovc, that is, don't change the video codec, and specify
-lavcopts vcodec=msmpeg4v2, that is change video codec to msmpeg.
Hard job to do, ins't it, changing the codec without changing it.
> 1. It does not have any audio even though the individual files have
Have you tried two files that use the same audio codec? I could imagine
that sound might be hard to play when it starts as stereo mp3 and changes
to ac3-surround midway in the file.

Presumably they all had the same audio codec.
when using -ovc copy -oac copy to concatenate files, make sure they have
codecs in the first place. Or re-encode them.
