Busy day - quick DVD

What a busy day!  Started out early with a Scout meeting for my son, then errands, a class at the hospital.  But I did manage to fit in 15 minutes of the Hot Hula beginning DVD.  I can't get the DVD to work on my 2 DVD players, only my laptop - so not idea - but still a good workout.  I need to try it at someone elses house, and then call the Hot Hula company and figure out what it doesn't work on DVD players.
