Thanks to both of you for your ideas--I should have known better to use

cat is sometimes underrated and sometimes overused.
If I see someting like `ls -l|cat` I am never sure if I should laugh or
cry.

The problem seems to be that 'cat' has been *so* misused during the
decades that people have actually forgotten its original purpose, and
thus they don't even think about using 'cat' in situations where it's
the exact tool for the problem. That is: concatenating files.

As for making a raw concatenation of two .avi files, the fact that it
seems to work is probably just a fluke. I'm assuming that the video
format that the .avi files are containing (after all, .avi is not a
video format itself, it's a container format for multimedia data) is
streamable, and mplayer/mencoder is, perhaps, skipping the header data
of the second .avi as garbage that doesn't belong to the stream.

The trick will probably not work properly for non-streamable video
data formats.
