Can anyone explain the why the Difference??
No, I can't. Ask TEAC.
But: check whether you have filled the tag for "Albumartist" - it could be that your TEAC reads these (and does not only rely on the filename as apparently your DVD player does) and groups the files by this tag. As the albumartist is probably empty or not there all the tracks look the same and so the TEAC uses the next sort criteria - which could also be "random".
Unfortunately you don't tell in which way the playing order differs on the TEAC.
So: try it whether filling the albumartist tag makes a difference. As this is easily done with MP3tag it shouldn't be too much of an effort.
