He said that the former didn't work in his situation.

I haven't tested mencoder with *.mpg so I don't know if it should work but
didn't in his case for some yet undiscovered reason.  I do know that I have
used the latter and it works fine.

Where I have used it... Say I create/convert a number of videos by calling
mencoder in a loop with the ultimate goal of combining some or all of them.
The latter is one way to do it without having to list out all of the
filenames individually.  Alternately I suppose you could just create a
string variable containing the names as you iterate through the loop and
then replace the `ls` statement with the variable.  I've never worked with
arrays in bash but perhaps that could also be a way to go if you are so

If there is a better way I am all ears.
