playlist does not display to the right of the display?

I was not able to display the playlist to the right of the right of the display. I tried to use 'Playlist width:' from node editing form but it had no effect. Eventually, 'Playlist width:' worked by changing displayheight to displaywidth in the second line bellow(flvmediaplayer.module, line 696):

// playlist stuff
flvmediaplayer_node_settings('flvmp_'. $node->type .'_pl_height', false, $node) ? $flashvars['displayheight'] =flvmediaplayer_node_settings('flvmp_'. $node->type .'_pl_height', false, $node) : null;
flvmediaplayer_node_settings('flvmp_'. $node->type .'_pl_width', false, $node) ? $flashvars['displayheight'] =flvmediaplayer_node_settings('flvmp_'. $node->type .'_pl_width', false, $node) : null;

This is in 5.x-0.9 version. Should that value be displaywidth or there is another way to display the playlist to the right?
