I am using the same user as when I run the script myself and it works
fine.  To my knowledge /tmp has full rights (drwxrwxrwxt) - I seem to
be able to do anything in this directory whatever user I am logged in
as.

I have tried this and it does not make any difference for me but I
have left this change in.

mplayer uses a fixed name of 00000002.jpg so its not needed in the
command.  I think the command also creates a 00000001.jpg (i.e. -f 2
two frames created).

ot sure how to do this.  The Perl script runs fine if run myself it
just does not run in cron so it should mean its setup correctly.

Any other ideas - I have posted a reply regarding my environment
variables a few minutes ago.
