Hi Rob!
Even though this is probably going to be over my head, I'd still like to
be able to access this 'movie'. The link you provided doesn't work for
me; it changes automatically to
https://pantherfile.uwm.edu/type/public/media/ME67-D10_ME67-LS10_LS10MicsSo=
r3_Lrg.mov
and gives 'error on page'.
Any suggestions please?
