In case anyone else has the problem I thought I would post just uploading the dop-player folder into the plugins folder doesn't work.
I had to have the files uploaded as follows:
After that just as the directions says, all you have to do is upload the FLV file and then select to insert it into a post. The video displays in posts automatically and the player is quite beautiful.
As the directions say you can customize the colors under Settings and that works out really well.
I did have other problems uploading FLV files over 2MB, but if anyone needs help on that issue see http://wordpress.org/support/topic/378498?replies=2
