VOBs are just MPEG2-Streams. MPEG-Streams can be concatenated as you
wish. The magic lies in the word "stream". Every information you need to
play an MPEG-stream is included in every header of the stream (every I
frame, if I am correct), so any player can connect to a MPEG-Stream and
start showing it.

AVIs are a different format, which *cannot* be concatenated easily, you
need a tool like avimerge or avisplit (from transcode, for example).

AVIs are not streamable, at least not without some very dirty magic or a
format like M$ ASF (Advanced Streaming Format).

I would guess, M$ created their MS-MPEG4, from which DivX was "derived",
so that it cannot be streamed, so to not produce an opponent to their
own ASF. (But this is only a wild guess.)
