Okay now I can see what I am doing wrong.
The mp3 file I am reading is not a file, it resides in a buffer in memory.
So I am opening it with ...

mpg123_init();
hMp3 = mpg123_new(NULL, &ret);
len = mp3BufSize;
mpg123_open_feed(hMp3);
ret = mpg123_decode(hMp3, (uchar*)mp3Buffer, len, out, 0, &tsize);

I grab the format and then switch to decoding using
mpg123_decode_frame(hMp3, &fNum, &bbuff, &bytes);
because I just want individual frames.

So it is the open feed and the decode frame that should not be used
together the way I am doing so.
mpg123 assumes it is reading a dynamic stream rather than a static
buffer and I guess it is that what is causing all the trouble.

Can you suggest/help/prod me on how I should open (mpg123_open()) when
the whole mp3 file is sitting in a buffer in memory as opposed to
being an external file?
